Laser effects on the skin. Thermal (burn) injury is the most common cause of laser induced skin damage. Thermal damage is generally associated with lasers operating at exposure times greater than 10 microseconds and in the wavelength region from the near ultraviolet to the far infrared.
Back pain; Bursitis; Carpal Tunnel Syndrome; Fibromyalgia; Healing With Cold Lasers . The cold laser produces an impulse of light at a specific wavelength (usually 600 to 980nm) that minimizes reflection and scattering but maximized absorption of the the energy (in photons) at a desired depth.
