Class 4 laser therapy gives a PT clinic a fast, non-invasive way to reduce pain, calm inflammation, increase range of motion, and support tissue repair—often in the same visit as manual therapy or exercise. Here is why so many practices add it.
1. Faster tissue repair and cell growth
Class 4 lasers can deliver a therapeutic dose deep enough to reach injured muscle, tendon, and ligament. That energy helps stimulate mitochondrial activity and ATP production, which supports quicker repair and a shorter recovery window for many musculoskeletal complaints.
2. Stronger pain relief
Laser therapy can reduce inflammation and help interrupt pain signaling at the treatment site. Many patients feel meaningful relief after one or two visits. For chronic problems, a focused course of about 6 to 12 treatments can change daily function and may reduce the push toward drugs or surgery.
3. Less inflammation and swelling
Improved local circulation and lymphatic flow help move fluid out of irritated tissue. That matters after injury, arthritis flare-ups, and repetitive-stress strain—and it often restores comfort and motion sooner.
4. Better circulation and oxygenation
Enhanced microcirculation brings more oxygen and nutrients to damaged tissue and helps clear metabolic waste. That is one reason laser pairs so well with therapeutic exercise and soft-tissue work.
5. Non-invasive and drug-free
Patients want results without another prescription. Class 4 laser therapy is non-invasive, typically comfortable, and drug-free, so it fits a conservative physical therapy model.
6. Useful across many PT conditions
The same platform can support sports injuries, arthritis, disc-related pain, neuropathy, and post-surgical rehab when used within your scope and the device’s cleared indications. That versatility makes it easier to justify the investment.
7. Shorter chair time, more complete sessions
Higher power means you can dose a joint, muscle origin/insertion, and nearby nerve pathways in a few minutes per area. That leaves more of the visit for movement, strengthening, and education.
8. A cash-pay service patients can feel
When results show up quickly, patients complete the plan of care and refer. Many clinics add laser as a scheduled add-on or package alongside standard PT.
Need help choosing the right Class IV laser for your physical therapy practice?
Our knowledgeable staff have decades of experience helping physical therapists, chiropractors, and rehab professionals integrate high-performance laser therapy.
Whether you treat sports injuries, accident-related trauma, geriatric patients, arthritis, neuropathy, joint and spine conditions, or general rehabilitation, a properly powered Class 4 system is one of the most useful tools for pain, inflammation, range of motion, and recovery speed.
Many PTs have moved over from LiteForce/LiteCure, Summus, K-Laser, and Aspen. The usual reason is simple: more usable power, a longer warranty, and full support in a turnkey package.
One clinician who previously owned two LiteCure lasers wrote:
“We tested the power of a REMY FX Elite 45W on a Gentec-EO Pronto 250 power meter, and there was indeed full power. Better than any other unit we’ve tested including Aspen, Diowave 60W, and Litecure 25/40W lasers. 10W → 10.2 | 20W → 20.4 | 30W → 30.1 | 45W → 45W. The FX Elite is a great laser and a wise investment for anyone offering high power laser therapy (HILT).” — Dr. Kraft, MD
Recommendation for PTs: get at least 30W for best clinical throughput. Buy the most power your budget allows. The REMY FX Elite 90W Quad is our top high-intensity package for high-volume PT.

Modern Class 4 laser therapy systems started with a single wavelength. Then they moved to a dual wavelength platform because each wavelength provides different therapeutic benefits. Now the 4-wavelength Quad laser is extremely popular because the combination of multiple wavelengths can deliver optimal results across a wide range of symptoms and conditions.
Customers frequently ask, “what are the best wavelengths?” Each wavelength interacts with tissue differently, offering unique benefits in terms of penetration depth, cellular response, and therapeutic outcomes. Below is a breakdown of the five most preferred gold-standard wavelengths used in advanced therapeutic lasers.
650nm is the classic red laser wavelength, widely recognized for its effectiveness in superficial and soft-tissue applications.
810nm is considered by many laser experts (including Dr. Michael Hamblin and Dr. Weber) to be the sweet spot for photobiomodulation (PBM).
915nm has gained strong popularity in advanced Class 4 systems for its powerful effects on circulation and nervous tissue.
980nm has been the most popular wavelength in Class 4 lasers for decades, prized for fast clinical results.
1064nm offers the deepest tissue penetration of all therapeutic wavelengths and is ideal for treating deep musculoskeletal and neurological structures.
At Class4Lasers.com, we specialize in advanced 4-wavelength Quad lasers that combine the most effective therapeutic wavelengths (typically 650nm, 810nm, 980nm and 1064nm or 915nm) in a single powerful system. These multi-wavelength devices allow you to treat superficial skin or nerve conditions, deep musculoskeletal, joint and spine issues, and everything in between — all with one versatile laser.
Here are our top Quad-wavelength Class 4 laser systems:
REMY FX Elite Quad Series (Premium High-Power Performance with 650/810/980/1064 Waves)
REMY Sport Series (Ideal for Physical Therapy & Sports Medicine with 650/810/980/915 Waves)

Class 3b lasers commonly deliver 100mW to 500mW of Power. There are 1000mW in 1 Watt. Class 4 therapy lasers typically start around 9 Watts and go up to 60 Watts. Over the last decade researchers and the medical community have been steadily raising the clinical dose for laser therapy. It has been revealed that the amount of energy or joules/cm2 that a body can handle to produce a significant clinical outcome is much more than was previously understood.
Class 4 Therapy Lasers are the optimum choice for numerous reasons and the most popular Class 4 Laser Therapy systems now range between 30 Watts to 60 Watts Continuous Wave (CW) and up to 90W peak power or more. Why? Because, higher power maximizes photon density, which dictates depth of penetration and overall saturation of target tissue at the root cause of the issue being treated.
Class4Lasers.com is the official manufacturers representative of numerous Class 4 Therapy Laser brands including REMY, and UltaLaser. Scroll down to review a comparison of different class 4 therapy lasers and see for yourself why Class 4 Therapy Lasers are rapidly gaining in popularity, in spite of some controversy over the years.
Want to have the option of higher dosage treatments, which is translated to more joules per cm squared (j/cm2) faster
Want to have the shortest treatment times (higher power translates to shorter treatment or more j/cm2 in a given time)
Want to treat larger areas such as in Neuropathy & Sciatica (due to fast treatments, can quickly move from one point to the next)
Want superior pain control through increased power and depth of penetration
Need to treat very deep areas (higher power density = deeper force of penetration)
Have a higher volume practice
Can afford a higher-end high performance laser
Wish to take advantage of tax reduction benefits
Class 4 laser therapy systems deliver the energy much faster than Cold Lasers and Class 3b lasers because they typically use fiber optics. Also, because of the high power output, they typically warm the tissue, which feels good to the patient and builds confidence, because it is obvious that the treatment is in process, compared to cold lasers, which don’t elicit much of a sensation. Dramatic pain relief and increased range of motion is often experienced within minutes as inflammation is reduced and a flood of photons creates nearly instant ATP in the cells. Additionally, pain blocking and feel good endorphins are released, which are like natural pharmaceuticals released from the brain to support healing, pain relief and mood elevation.
In cases where the energy needs to be delivered over a large or deep area, the extra power from a Class IV therapy laser (30-60W) keeps the total treatment times at less than 12 minutes, with some locations needing only 1-3 minutes and an average treatment is approximately 5-6 minutes (45W-60W Models). Practitioners gain the ability to cover more areas and support consistently positive clinical outcomes. The extra power also allows practitioners to deliver class 3b dosages in just seconds to a couple minutes or go to higher dosages for superior pain control. All these class 4 systems can deliver medium dosage like you get in a higher quality class 3b system, but you also have the choice to treat larger areas faster and deeper, and provide more consistent, faster pain control.
Over the years, there has been some controversy in the therapy laser market about class 4 lasers and their performance vs safety when compared to lower power cold lasers. This controversy is mainly driven by class 1 – 3b cold laser manufacturers spending their money and time downplaying their higher powered competition, to scare people away from what is often a superior product.
In the last decade we have sold thousands of class I, II, 3R and 3B cold laser options. The fact is, until just 9 years ago, Class IV therapy lasers were typically $30,000 to $90,000 and not a practical investment for the average practice.
What we have done with Remy, Remy FX and UltaLaser PBM Pro is raise the bar. Much more power, more feature, better warranty and significantly lower price per Watt. We understand that class 4 laser therapy systems are not for everyone, however, now that we have been able to bring prices down by 30-60%, there is really no reason to not get a class 4 laser.
Practitioners are getting wise to the many undeniable benefits of Class IV Laser Therapy and making it available to clients has become a “game changer”. If you are looking for a Class 4 laser with the best FDA Clearance, Remy Sport and Remy FX are exceptional with FDA/510k.

Class 4 laser systems are just like other lower power systems except they deliver the energy faster and deeper with a higher concentration of energy. The higher power pushes the energy faster so that you can get to your target dosage (at depth) in a shorter time. It is the wavelength of light that determines the efficiency (based on RATS: reflection, absorption, transmission, scatter) at pushing the energy deep.
For PBM the goal is to deliver maximum energy at depth, and get a photo-chemical reaction. Thus, you want one of your high power wavelengths to be in the 810nm range (10, 15 or 30 Watts). This is the wavelength with the highest efficiency at producing a photo-chemical reaction in tissue. Now commonly referred to as Photobiomodulation or PBM for short. 810nm is the gold standard for PBM.
In cases where the energy needs to be delivered over a large problem area, this extra power keeps the treatment times at a fraction of the time compared with class 1 through 3. The average class 4 therapy laser is 20 to 100 times more powerful than a lower power cold laser.
Dosage equals average power X treatment time, so if you are targeting the same dosage, a 10-watt laser will accomplish in 1 minute what it takes 1-watt to accomplish in 10 minutes. A 30 Watt laser is 150x more powerful than a 200mW cold laser.
The extra power of Class 4 lasers allows practitioners to deliver class 3b dosages in just 1-3 minutes or go to higher dosages for superior pain control and rehabilitation. You can also use the extra power to distribute energy over a larger area, which helps reduce inflammation and accelerate healing, to help patients feel better faster. This is nicely accomplished with a laser multi-roller, or glass round face handpiece, allowing for a soothing laser massage over an extended area to dramatically reduce inflammation, increase blood circulation, move chi along meridians and distribute photonic energy over a wide area.
If desired, class 4 laser therapy systems can deliver medium dosage such as you get in a class 3b system and lower power systems, but class 4 systems give you the choice to treat larger areas, deeper areas, do shorter treatment times and provide superior pain control. It is up to the practitioner to decide how to use the laser. Since some practitioners also like to acupoint therapy, many of the above listed lasers include a 7mm acupoint biostimulation handpiece. Typically the laser would be turned down to 500mW or less and then the practitioner can safely and effectively treat body and ear points in 10-30 seconds.

They are more expensive than class 1 to 3b systems
They must be kept moving (in general) if delivering over about 1 joule/second/cm²
They pose a higher potential risk of injury to the eyes if not used correctly (This is extremely low if everyone wears safety glasses)

At Class4Lasers.com, success with therapeutic lasers comes from understanding the science behind the technology. Patients often seek a quick “laser zap” for instant relief. While not magic, many experience meaningful pain reduction after the first session, with cumulative benefits building over time—reduced inflammation, improved range of motion, and faster healing of tissues, wounds, joints, spine and other conditions.
This primer covers the core principles: how lasers work, key technical factors, 3 primary laser delivery systems, and why power and energy delivery make a significant difference in clinical outcomes. Critical factors that affect the consumer when determining what kind of laser to buy and how much power or joules of energy is actually being delivered with a cold laser, super pulsed laser or Class 4 laser.
L.A.S.E.R. stands for Light Amplification by Stimulated Emission of Radiation. True therapeutic lasers generate coherent, directional light through controlled stimulated emission. Unlike ordinary bulbs or LEDs, laser photons are synchronized, allowing better tissue penetration and therapeutic effect.
If the emitting source looks like a standard bulb, it is not a laser. Bundling LEDs does not produce coherent laser light. Laser diodes may be combined with LEDs to increase total output, but coherent laser light remains superior for most deep-tissue applications. Some LED products can still provide benefits, but the vast majority of LEDs only treat superficial skin, or open wound conditions.
Important Reminder: Always select FDA-cleared lasers. Non-cleared devices purchased overseas may lead to regulatory complications or confiscation.
Coherence is essential for effective treatment. Laser light emits photons in a synchronized, directional manner so they penetrate deeper into tissue with minimal scattering or reflection, unlike the scattered waves from incoherent LEDs or bulbs.
Questions to Ask When Evaluating a System:
Therapeutic lasers are effective for pain relief, inflammation reduction, accelerated tissue repair (tendons, bone, skin, nerves, muscle), immune stimulation, improved lymphatic drainage, increased collagen production, and neurological support.
Mechanism at the cellular level: Laser photons penetrate the skin and are absorbed primarily by cytochromes in the mitochondria. This boosts ATP (adenosine triphosphate) production, restoring normal metabolism in damaged cells and triggering a cascade of biological effects including anti-inflammation, analgesia, and tissue regeneration.
Effective deep-tissue therapy occurs within the therapeutic window of approximately 600–1200 nm. In this range, light penetrates water-rich tissues efficiently with low absorption by water, hemoglobin, or melanin. Wavelengths of 650, 810, 915, 980 and 1064nm are considered the “Gold Standard” wavelengths. Why? Because they are each particularly valued for excellent health and therapy benefits. 650nm for soft tissue issues, anti-inflammatory, antibacterial, and helpful for rapidly increasing wound and ulcer healing, skin care, post op, acne and much more. The other wavelengths are the optimal infrared wavelengths: 810nm for Photobiomodulation (PBM) which maximizes conversion of photons to ATP for cellular energy, 915nm for Nitric Oxide, 980 for rapid analgesic pain relief and inflammation reduction and 1064nm for healing and ATP at maximum depth in musculoskeletal conditions and brain issues (TBI), as it is the longest wave and is not absorbed by melanin at the skins surface, allowing for direct penetration through the dermis layers.
Power is measured in milliwatts (mW) or Watts (W) — 1,000 mW = 1 W.
Cold lasers (typically Class 3 / Low-Level Laser Therapy) deliver very low average power — usually under 500 mW and often only 10–100 mW — even if they advertise high peak power in pulsed modes. This severely limits total energy delivery and treatment efficiency.
Class 4 therapy lasers provide much higher average power (commonly 10–60 W in CW mode), enabling deeper penetration, faster treatments, and significantly greater energy delivery.
Energy Delivery Example (5 minutes of treatment):
This substantial difference in joules allows Class 4 lasers to treat larger areas more quickly, reach deeper tissues effectively, and produce faster clinical results for pain and inflammation. Cold lasers remain useful for superficial or highly sensitive cases, but Class 4 systems are generally preferred for musculoskeletal and high-volume practices.
Practical Tip: Always focus on average power and actual joules delivered rather than peak power claims or class rating alone.
Dispelling the Myth: The Arndt-Schulz Law and “Diminishing Returns” in Therapeutic Laser Energy
One of the most commonly cited concerns in laser therapy discussions is the Arndt-Schulz Law (sometimes spelled Arndt-Schultz), an idea from the late 1800s that is frequently misinterpreted to suggest there can be “too much” therapeutic laser energy — leading to diminishing returns or even inhibition of healing.
Originally developed from studies on chemical toxins and yeast cells, the law proposed a biphasic (two-phase) response:
In the context of photobiomodulation (laser therapy), this concept evolved into the biphasic dose-response curve (often called the Arndt-Schulz curve). It is sometimes used to argue that low-level “cold” lasers (Class 3, typically under 500 mW) are safer or more effective, while higher-powered Class 4 lasers risk pushing tissues into an “inhibitory” zone.
The original Arndt-Schulz observations were based on chemical poisons, not light. When applied to laser therapy, the concept has been significantly over-extrapolated and, in many cases, used as marketing to favor low-power devices.
Modern research — including foundational work by Tiina Karu, PhD, and extensive reviews by experts like Michael Hamblin — shows that the dose-response relationship in photobiomodulation is more nuanced than a simple bell-shaped curve with one peak and one inhibitory zone. Karu demonstrated that the response actually includes multiple peaks and valleys, and the idea that “more energy is automatically harmful once a certain point is reached” does not hold true across the wide range of conditions treated with therapeutic lasers.
Importantly:
In short: the outdated strict interpretation of the Arndt-Schulz Law is often used to create fear around higher-powered lasers. Current evidence supports that, when used correctly, Class 4 systems provide faster, deeper, and more effective photobiomodulation without crossing into inhibitory territory. The focus should always be on optimal energy delivery to the target, not on an outdated 19th-century chemical model.
Practical Takeaway for Practitioners Rather than worrying about “diminishing returns,” evaluate lasers based on real-world factors: average power, coherence, wavelength within the therapeutic window, and the ability to deliver clinically effective joules quickly and safely. Higher average power (Class 4) simply makes it easier to reach the sweet spot of the biphasic curve for most deep-tissue applications.
This updated understanding aligns with the science of photobiomodulation and helps explain why properly applied Class 4 laser therapy continues to deliver excellent clinical results for pain relief, inflammation reduction, and accelerated healing.

Discover the difference that the right laser therapy system can make — for your practice and for your patients.
Laser therapy continues to gain popularity in chiropractic, physical therapy, pain management, and rehabilitation practices. Whether it’s high-powered Class 4 laser therapy for deep tissue penetration, cold laser (low-level laser therapy or LLLT/photobiomodulation) for cellular healing, infrared modalities for superficial warmth and circulation, or attended sessions requiring constant provider supervision, these treatments offer patients a non-invasive, drug-free option for pain relief, inflammation reduction, and tissue repair.
However, billing for these services remains nuanced. As of 2026, there is still no dedicated Category I CPT code specifically for most non-surgical therapeutic laser applications. Practitioners must rely on a handful of established (and sometimes unlisted) codes, each with its own nuances, documentation requirements, and payer acceptance. This educational post breaks down the most commonly used codes, how and why practitioners select them, the ongoing reimbursement hurdles many face, and why a growing number of clinics are successfully offering laser therapy as a cash-pay service to create a reliable extra income stream.
Proper code selection depends on the device class, treatment parameters, attendance level, and clinical indication.
Here are the codes practitioners most frequently report, along with typical use cases and rationale:
| Code | Description | Best For | Why Practitioners Use It | Typical Notes / Reimbursement Reality |
|---|---|---|---|---|
| 97039 | Unlisted modality (specify type and time if constant attendance) | Class 4 / High-power laser; most attended laser sessions | Most flexible “catch-all” for therapies without a specific code. Allows detailed narrative (e.g., “attended Class 4 laser therapy, 810–980 nm, 10–15 W”). | Requires robust documentation. Many Class 4 laser manufacturers recommend this as the primary code. |
| 97037 | Application of a modality to 1 or more areas; low-level laser therapy (nonthermal and non-ablative) for post-operative pain reduction | Cold laser / LLLT in post-op settings | Specific to LLLT and post-surgical pain. More descriptive than unlisted codes. | Medicare often assigns “N” (non-covered) status due to NCD 270.6. Some private payers reimburse $25–$50/session. |
| 0552T | Low-level laser therapy, dynamic photonic and dynamic thermokinetic energies, provided by a physician or other qualified health care professional | Certain LLLT / cold laser protocols (especially those with specific device features) | Category III code introduced for emerging photobiomodulation techniques. Sometimes billed in 15-minute increments. | Helps track utilization for potential future Category I status but frequently denied as experimental (“M” status by Medicare). |
| S8948 (HCPCS, not CPT) | Application of a modality (requiring constant provider attendance) to one or more areas; low-level laser; each 15 minutes | Time-based attended LLLT / cold laser | Clear time component makes it straightforward for attended sessions. | Popular with some private insurers ($20–$50+ per unit); Medicare does not recognize it (“I” status). |
| 97026 | Application of a modality to 1 or more areas; infrared | Infrared light/heat therapy | Historically used for infrared devices or low-level photonic stimulation. | Often discouraged for true laser therapy; payers may bundle it with heat-lamp codes and reimburse poorly or deny. |
Other occasionally used codes:
Important 2026 note: The annual therapy code updates focused on new remote therapeutic monitoring (RTM) codes (e.g., 98979, 98984, 98985) rather than laser modalities. No new dedicated laser codes were added.
Despite the clinical benefits patients report, insurance reimbursement for therapeutic laser remains inconsistent and often frustrating:
These realities lead many practices to spend significant time on appeals or write-offs, prompting a strategic shift.
Because of reimbursement hurdles, a large and increasing number of practitioners now offer laser therapy primarily (or entirely) as a cash-based service. Patients are often highly motivated to pay out-of-pocket—typically $50–$150 per session or $500–$1,500 for package deals—when they experience meaningful results without drugs, injections, or surgery.
Why this model works so well:
Many chiropractic and PT clinics have turned laser into a significant profit center while still billing insurance for other parts of the visit when appropriate. The key is transparent pricing, clear patient education on expected outcomes, and offering convenient packages or financing.

Laser therapy remains a powerful tool in modern rehabilitation. While insurance billing can be challenging, the clinical results—and the willingness of patients to invest in them—make it a smart addition to many practices. Whether you bill insurance when possible or embrace cash-pay, the focus should always be on delivering exceptional patient outcomes.

In the world of non-invasive pain management and rehabilitation, Class 4 laser therapy stands out as a versatile and highly effective treatment. Whether you’re dealing with chronic pain, sports injuries, or post-surgical recovery, this advanced modality offers remarkable results by addressing pain, inflammation, and tissue repair at the cellular level.
Laser therapy delivers a wide range of therapeutic benefits that go far beyond simple symptom relief. It is widely used to:
These effects make Class 4 laser therapy an excellent choice for treating musculoskeletal issues, soft tissue injuries, chronic wounds, and even nerve-related conditions.
One of the most fascinating aspects of laser therapy is how a single treatment can positively influence so many different types of tissue — from muscle and tendon to bone, skin, and nerves. The secret lies in its action at the intracellular level.
When the laser is applied, it emits photons (packets of light energy) that painlessly penetrate the skin and reach deep into the cells. These photons are absorbed primarily by cytochromes — specialized receptors within the mitochondria, the energy powerhouses of the cell.
This absorption converts light energy into chemical energy, triggering a cascade of beneficial reactions:
As a result, the body experiences measurable improvements such as higher levels of enzymes, growth factors, and beneficial cellular products, angiogenesis (formation of new blood vessels), and reduced formation of fibrous (scar) tissue — especially helpful for chronic wound healing.
The downstream benefits of these cellular changes are impressive and well-documented:
Laser therapy doesn’t just mask pain — it addresses it through several powerful physiological mechanisms:
These combined actions lead to effective, drug-free pain relief while promoting true healing rather than temporary symptom suppression.
Class 4 lasers (also known as high-intensity or high-power lasers) deliver significantly more energy than lower-level Class 3 or “cold” lasers, making them a superior choice for many clinical applications. Here’s why practitioners and patients increasingly prefer Class 4 lasers for the application of Class 4 laser therapy:
In short, Class 4 laser therapy combines power, depth, and efficiency to deliver noticeable improvements faster and more consistently than lower-level alternatives.

Discover the difference that the right laser therapy system can make — for your practice and for your patients.
For more than 60 years, researchers and clinicians have refined laser therapy techniques. Today, thousands of forward-thinking practitioners worldwide are integrating Class IV lasers into their practices, delivering faster pain relief, reduced inflammation, and accelerated healing — without drugs, surgery, or downtime.
While low-level lasers (LLLT/Class 3) remain useful for superficial applications, Class IV lasers deliver significantly higher power output (typically 10–60 watts) and superior tissue penetration. This enables deeper therapeutic effects in shorter treatment times, producing more profound clinical outcomes for both acute and chronic conditions.
Modern research has largely discredited the outdated Arndt-Schulz Law (which suggested that higher doses of stimulation would produce diminishing or inhibitory returns). Contemporary studies show that higher-powered Class IV lasers, when properly dosed and administered, deliver superior biostimulatory effects without the inhibitory outcomes predicted by the old theory. We now understand that maximizing safe and effective photon density with higher power lasers produces superior results faster in the majority of musculoskeletal issues. Higher irradiance allows for deeper penetration and more efficient photobiomodulation at the cellular level, especially in larger or deeper target tissues.
Key Clinical Benefits Include:
Laser therapy is now a mainstream modality trusted by tens of thousands of healthcare providers — including physical therapists, chiropractors, medical doctors, veterinarians, and acupuncturists. It received FDA clearance for multiple indications starting in 2002 and is supported by over six decades of cumulative research.
Important Disclaimer: Individual results vary. We do not make medical claims beyond the specific indications cleared by the FDA for Class IV therapeutic lasers (primarily temporary relief of minor muscle and joint pain, arthritis, and inflammation).
Hundreds of high-quality, randomized, double-blind, placebo-controlled studies support the efficacy of photobiomodulation. Positive outcomes have been documented for:
These findings — along with thousands of additional peer-reviewed papers — show that properly dosed Class IV laser therapy can reduce pain and inflammation, improve circulation, stimulate cellular repair (via increased ATP production), and accelerate tissue regeneration.
Adding Class IV HILT to your clinic is both clinically superior and financially strategic. It:

Class IV laser therapy is a cutting-edge, non-invasive treatment that leverages high-powered laser energy to accelerate healing, reduce inflammation, and alleviate pain across a wide range of conditions. From chiropractors and physical therapists to podiatrists and other practitioners, Class IV laser therapy is revolutionizing patient care by delivering rapid, effective results without the need for drugs or surgery.
This article compiles peer-reviewed clinical studies demonstrating the efficacy of Class IV laser therapy, along with real-world outcomes observed in clinical practice. It is designed to help practitioners understand the science-backed advantages of integrating Class IV laser therapy into their clinics.
Class IV laser therapy, also known as high-intensity laser therapy (HILT), uses focused light energy at specific wavelengths (typically 650–1064 nm) to stimulate photobiomodulation (PBM). This process enhances cellular metabolism by increasing ATP production, improving circulation and nutrient transport, and reducing inflammation. These effects promote faster tissue repair and pain relief.
Unlike low-level laser therapy (LLLT/Class III), Class IV lasers deliver significantly higher power outputs (>500 mW), enabling deeper tissue penetration and quicker therapeutic outcomes, often in just 2–10 minutes per session.
The following studies highlight the robust clinical evidence supporting Class IV laser therapy for conditions commonly treated by chiropractors, physical therapists, and podiatrists.

Findings: Class IV laser therapy (810 nm) reduced neuropathic pain by 60% and improved nerve function in patients with chronic conditions.
Implication: A powerful tool for podiatrists and physical therapists treating neuropathy.
The studies above, spanning conditions from chronic pain to wound healing, demonstrate that Class IV laser therapy consistently outperforms LLLT and other modalities due to its higher power output and deeper tissue penetration. Treatments are quick (5–10 minutes), non-invasive, and carry minimal side effects, with most patients experiencing only a mild warming sensation, along with reduction of pain and increased range of motion. The FDA has cleared Class IV lasers for pain relief and muscle relaxation, and their versatility makes them indispensable for practitioners.
Testimonial 4: John, 38, Construction Worker
“I had debilitating low back pain from a work injury that kept me off the job. My physical therapist used a Class IV laser, and after just two sessions, I felt significant relief. By the end of the treatment plan, I was back to work full-time. This therapy saved my livelihood!”
For Chiropractors, Class IV laser therapy excels in treating spinal conditions, arthritis, and soft tissue injuries. Physical therapists benefit from its ability to enhance recovery in musculoskeletal disorders and postoperative rehabilitation. Podiatrists find it particularly effective for plantar fasciitis, diabetic ulcers, and neuropathy. The ability to customize power settings (0.5–25W) and wavelengths (e.g., 660 nm for superficial tissues, 810–1064 nm for deeper structures) allows tailored treatments for diverse patient needs.
Moreover, integrating Class IV lasers into your practice can create a new revenue stream. A single session typically costs $50–$150, with packages of 10–12 treatments reducing the price per session, making it an attractive cash-based service. Patients often report immediate relief, increasing satisfaction and referrals.
Class IV lasers are safe when used by trained professionals, with no risk of burns due to their photochemical, not thermal, action. Protective eyewear and adherence to dosage protocols ensure safety. Concerns about overstimulation or delayed healing are unfounded, as studies show no adverse effects on tissue repair. However, insurance may classify Class IV laser therapy as “experimental,” so practitioners should emphasize its cash-pay potential.
Testimonial 5: Emily, 29, Runner
“Plantar fasciitis sidelined me from running for months. My podiatrist recommended Class IV laser therapy, and after five sessions, the pain was gone, and I was back to training. The treatments were quick, painless, and worth every penny!”
The evidence is clear: Class IV laser therapy is a scientifically validated, versatile, and patient-friendly solution for pain management and tissue healing. With over 6,000 studies supporting photobiomodulation, including the 14 highlighted here, practitioners can confidently adopt this technology to enhance outcomes and grow their practices. Whether you’re a chiropractor addressing chronic back pain, a physical therapist rehabilitating sports injuries, or a podiatrist treating foot conditions, Class IV lasers offer a competitive edge.

At Class4Lasers.com, we frequently get asked to compare high-power Class 4 therapy lasers like our flagship REMY FX ELITE 90W with other systems on the market, including the Phoenix Thera-Lase. Both are FDA-cleared Class IV devices, but they differ dramatically in design philosophy, power delivery, versatility, and real-world performance.
The REMY FX ELITE 90W is built for maximum photobiomodulation (PBM) depth and speed with true high continuous wave (CW) output and multi-wavelength synergy. The Phoenix Thera-Lase, while effective for superficial heating, is a single-wavelength CW system with significantly lower power and fewer features.
Here’s a clear, no-nonsense side-by-side breakdown based on verified FDA clearances (Phoenix K151521: 35W @ 1064nm) and current REMY specs.
| Feature | REMY FX ELITE 90W | Phoenix Thera-Lase System |
|---|---|---|
| Peak Power | 90 W (pulsing modes and CW modes) | 35 W output |
| Max Continuous Wave (CW) | 60.3 W true CW (sustained high power) | 35 W CW |
| Average Power | Up to 60.3 W CW; highly efficient dosing | up to 35 W CW maximum |
| Power Type | True CW + advanced pulsing (sweep, single, multi-step up to 12 frequencies) | CW, Single, Repeat (basic pulsing) |
| Total Energy Delivery | 8,000–11,000+ Joules in 8–14 min | Lower total Joules due to 35 W cap; longer sessions required |
Key Takeaway: REMY delivers nearly double the sustained CW power (60.3 W vs. 35 W), meaning faster, deeper treatments with more total energy (Joules) per session. Superpulsing claims (high peaks/low average) are often marketing hype—REMY’s true high CW provides consistent, clinically superior photobiomodulation without gimmicks.
| Feature | REMY FX ELITE 90W | Phoenix Thera-Lase System |
|---|---|---|
| Wavelengths | Quad: 1064 nm IR plus: 650 nm red + 810 nm and 980 nm |
Single: 1064 nm IR |
| Penetration Depth | Up to 6+ inches (multi-wavelength synergy) | Claimed up to 6 inches (marketing); FDA limits to topical heating |
| Beam Size / Handpieces | Large-area (30 mm Zoom + 40 mm), deep-tissue, roller, hands-free options | 0.75–1.88 inch diameter wide beam (non-contact) |
Key Takeaway: REMY’s quad-wavelength system lets you blend for superficial (skin/wounds) and deep (joints/spine/nerves) issues simultaneously. Phoenix’s single 1064 nm is more limited to heating and inflammation—great for some applications, but far less versatile.
| Feature | REMY FX ELITE 90W | Phoenix Thera-Lase System |
|---|---|---|
| Modes | CW, Pulsing (sweep up to 20,000 Hz, 12-step), ISMART adaptive protocols | CW, Single, Repeat (basic pulsing) |
| Software | WiFi-updatable Android OS, dozens of preloaded protocols (human/animal, adapts to skin type/size), 11″ touchscreen | Touchscreen remote controller for mode/timer/power; no WiFi updates or advanced protocols |
Key Takeaway: REMY’s modern, updatable software with 80+ smart protocols makes it future-proof and incredibly easy to use. Phoenix is simpler but lacks depth and adaptability.
| Feature | REMY FX ELITE 90W | Phoenix Thera-Lase System |
|---|---|---|
| Included Accessories | $6,000–$7,000 Success Package: multiple handpieces (zoom, deep-tissue, roller, hands-free), hard case, 3 pairs eye protection, Dr.-led live Zoom training/certification (up to 6 staff + CME credits), customized marketing kit, bonus eBooks, free insured shipping | Laser module, remote controller, fiber cable/handpiece (limited variety; no training/marketing package standard) |
| Warranty | 5 years (parts/labor, Florida service center, <1 week turnaround, white-glove shipping paid both ways) | 3 years (parts/labor, per reseller sites) |
| Price (approx.) | $24,995 (special pricing + financing options) | $20,000–$30,000 (estimates; varies by seller) |
Key Takeaway: REMY includes everything needed for immediate success—training, certification, marketing, and lifetime support. Phoenix is more device-focused, often requiring extra investment in setup and promotion.
Verdict: REMY’s high CW output and multi-wavelength flexibility provide superior photobiomodulation, faster sessions, and better outcomes for pain, inflammation, neuropathy, arthritis, sports injuries, and spine/joint issues.
The REMY FX ELITE 90W is like having four powerful lasers in one system—synergistic wavelengths create a quantum healing effect single-wavelength devices can’t match.

Today, we’re diving into a head-to-head comparison between the MLS M7 Super Pulsed Laser from Cutting Edge Lasers and the REMY FX Elite 90W Quad Laser from Discover Lasers LLC. While both are advanced tools for pain relief, tissue healing, and rehabilitation, we’ll explore why the REMY FX Elite 90W stands out as the superior, more affordable choice for chiropractors, physical therapists, and other professionals seeking a turnkey, high-performance solution.
NOTE: Above Picture is a comic and not a true depiction of what the lasers look like.
At Class4Lasers.com, we pride ourselves on offering factory-direct pricing and comprehensive packages that deliver unmatched value.
Let’s break down the key differences in power, wavelengths, features, pricing, benefits, results, and more—backed by real specs and user insights.
Power is often the first spec professionals look at, but it’s not just about peak numbers—it’s about how much usable energy reaches the target tissue.
Why REMY Wins: The REMY’s higher effective power means quicker therapeutic doses to deeper targets (e.g., 6cm vs. the M7’s and M6’s shallower reach). Professionals report superior pain relief and healing in fewer sessions with REMY, making it ideal for a busy practice that takes pride in delivering superior results for patients.
Wavelengths determine how laser energy interacts with tissues—shorter for surface-level, longer for deeper penetration.
Why REMY Wins: The quad-wave setup covers a broader spectrum of conditions, from superficial wounds to deep joint issues. Users like Dr. Pan, DC, praise its “mind-boggling results” for everything from low back pain to animal treatments, far outpacing the M7’s limited wavelengths.
What you get out of the box matters for seamless integration into your practice.
Why REMY Wins: The REMY’s turnkey setup eliminates hidden costs. Dr. Terry, DC, calls it “everything you need for success,” including marketing materials and ongoing support—features that make it plug-and-play compared to the M7’s more basic inclusions.
Cost is a critical factor for ROI.
Why REMY Wins: Factory-direct pricing makes the REMY a steal—half the cost of comparable systems without sacrificing power or features. Professionals like Dr. Force, DC, note it’s “half the price of LiteCure/Summus” while delivering more.
Real-world performance separates good from great.
Why REMY Wins: Shorter sessions mean higher throughput and happier patients. Dr. Ivar Roth, DPM, reports “quicker treatments for larger patients,” and over 1,000 successful cases from Dr. Julie Scott, DC, underscore its edge over the M7’s slower, lower-power delivery.
Safety is paramount in laser therapy.
Why REMY Wins: Built-in training empowers users for “superior, reproducible results with every patient,” as emphasized by Dr. Murphy, DC—far beyond the M7’s basics.
While the MLS M7 offers innovative robotic features and consistent non-thermal therapy, it falls short in effective power delivery, wavelength versatility, photon density, depth of penetration, speed of effective treatments, and overall value. The REMY FX Elite 90W Quad Laser excels with higher usable energy, more premium wavelengths, much higher CW power, more versatile handpieces, a comprehensive turnkey package that includes a customized marketing portfolio for the practitioner, a 5 year white glove warranty, and unbeatable pricing—making it the best buy for professionals who want top-tier results with a rapid ROI that you can take to the bank.

Don’t just take our word for it—here’s what real chiropractors are saying about the impact the REMY laser has had on their patients and practices.
– Dr. Kevin Murphy, D.C.
“Good afternoon, I just want to take some time to reach out and express my overwhelming satisfaction with your product. I purchased the Remy laser in September 2025 and have been using it for many different conditions. I am not only using it for acute and chronic pain but I have had significant success when using it to help neuropathy patients and patients who suffer from different forms of nerve damage due to trauma or medical conditions. Some of my patients have been able to lower their dose of RX pain meds and 2 of my patients no longer take anything and come once a month for continued treatment.
I have a 40-year-old female who had permanent nerve damage from Bell’s Palsy of 15 years. The patient had no taste or smell due to the nerve damage along with unequal facial symmetry. After 3 visits, patient taste and smell came back along with close to 50% improvement in control of her facial muscles. Patient completed 7 treatments and has her full taste back and smell along with having to get new glasses due to her vision improving and hearing. Patient has close to 90% facial symmetry.
A second patient came in with shingles that extended from her L4/L5 region down the posterior left leg to her feet. Patient had multiple open sores that ranged from the size of the palm of her hand to the size of a needle point. Patient unable to take meds to help due to allergies. The patient had been in excruciating pain for 1 week. After the first treatment pain had decreased by 50% per patient and after the second treatment 2 days later she was pain free and almost 75% of the redness around the open sores were gone. 5 total visits and there was no sign of the rash or scars.
I am currently working with a patient that had a benign tumor removed from her posterior aspect of her left ear 28 years ago that was the size of a lemon. The patient has had permanent facial nerve damage since the procedure. Patient has no hearing out the left ear. We started her first treatment today.
I also started today with the first treatment of a male patient referred by his neuro surgeon for laser therapy post surgical fusion of the L4/L5 and L5/S1 for pain control.
I will let you know how the last two do along with progress. One of the greatest aspects of this laser purchase beyond the equipment, is the exceptional service and support that follows the purchase of the equipment. Being able to reach Dr Z anytime I need his advice or input on a patient is outstanding. He has been there for me. Always willing to teach and advise. To me that is by far the greatest part of my purchase. Thank you for all you do and always being there for support.”
– Dr. Kevin Murphy, D.C.
These dramatic improvements in nerve-related conditions highlight the deep-tissue penetration and photobiomodulation power of the REMY laser—especially in higher-wattage models like the 90W.
– Dr. Julie Scott, DC
“I’ve been in practice for 27 years and the class IV Remy laser is the best physiotherapy tool I’ve ever used. I’ve used it on an acute disc, chronic disc, strain, sprains, plantar fasciitis, bursa problems, rotator cuff tears, etc. It’s even effective on my peripheral neuropathy patients.
I’ve used it successfully on over 1000 patients with only 3 to 4 unresponsive, and that’s it! I would recommend it to any practitioner!”
– Dr. Julie Scott, DC
With a track record like this, it’s clear why chiropractors call the REMY laser a must-have for everyday musculoskeletal complaints and stubborn chronic issues.
– Dr. Edward Pan, DC
“My practice has benefited greatly from purchasing the Remy FX Elite 90W laser. The results I am getting is mind boggling. I have used many modalities in my chiropractic office and this hands down, gets the best and fastest results.
I love the fact that this laser works on all kinds of conditions from acute low back pain to chronic knee and shoulder issues, and even works on animals. My patients feel instant relief after each session. Also, because I have the 90W model (most powerful laser out there) the sessions are short, which gives me time to attend to other things. It’s easy to use and you can teach the staff to do it.
I highly recommend Remy Laser. The customer support is amazing!”
– Dr. Edward Pan, DC
