optical maser
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).
