An optical source that emits photons in a coherent beam. Light Amplification by Stimulated
Emission of Radiation (LASER) is brought about using devices that transform light
of varying frequencies into a single intense, nearly nondivergent beam of monochromatic
radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions
of the spectrum
Note publique d''information :
The microwave equivalent of LASERS
Note générale sur le champ d'application :
general or unspecified; prefer specifics; laser injuries = LASERS /adv eff + organ
/ inj but do not coordinate with RADIATION INJURIES or any BURNS term; effect of laser
as radiation: coordinate IM with anatomical term, organism or chemical substance /
rad eff (IM); LASER THERAPY and LOW-LEVEL LIGHT THERAPY are also available
