Therapeutic Lasers and Wavelengths Explained

There are 3 main categories that people use to compare therapeutic laser systems:  • Power density (measured in milliwatts [mW] for class 1-3b and watts [W] for class 4 laser systems)  • Wavelength (measured in nanometers [nm]) or Wavelengths (when multiple wave forms are used in the same laser) • Pulsing, which includes: Pulsed laser (PL), […]
