  laser \laser\ n. [acronym from Light Amplification by Stimulated
     Emission of Radiation: ca. 1955.]
     A device which produces an intense, usually narrow,
     monochromatic beam of coherent light; called also {optical
     maser}. It has various forms, and is used in various
     applications in science and technology. The beam is produced


     by boosting the majority of the electrons in specific
     radiation-absorbing atoms in a medium into a higher energy
     level, from which they are stimulated by their own emitted
     radiation to drop back synchronously to their lower energy
     level, and emit light which is in phase (coherent).
  
     Syn: optical maser.
