LASER-Light Amplification by Stimulated Emission of Radiation

ABSTRACT

Laser, a device that stimulates atoms or molecules to emit lightat particular wavelengths and amplifies that light, typicallyproducing a very narrow beam of radiation. The emissiongenerally covers an extremely limited range of visible,infrared, or ultraviolet wavelengths. Many different types oflasers have been developed, with highly varied characteristics.Laser is an acronym for “light amplification by the stimulatedemission of radiation.” In that manner, they can confidentlymake appropriate decisions as to the best device to use on apatient (or the best device to purchase for a practice).
