| laser |
An acronym standing for Light Amplification by Stimulated Emission of Radiation. The medium that "lases" may consist of a gas (encased in a tube) or a solid material. Photons are emitted when the medium is stimulated by an electromagnetic field, which may be produced by an electric current or by an intense light source. A laser emits radiation at a characteristic set of wavelengths, depending in part on the composition of the lasing medium as well as mechanical or optical design factors.
