Definition: Light amplification by stimulated emission of radiation. This phenomenon is caused by devices that transform light of varying frequencies into a single, intense and almost non-divergent beam of monochromatic radiation. Lasers operate in the visible, infrared or ultraviolet regions of the spectrum. They are capable of producing immense heat and power when focused at close range and are used in surgical procedures, diagnostics and physiological studies. Lasers used at low power, transmitting light rather than heat, have been used in wound healing and pain control (LASER THERAPY, LOW LEVEL).
