Maser - Wikipedia
WEBA maser is a device that produces coherent electromagnetic waves (microwaves), through amplification by stimulated emission. The term is an acronym for microwave amplification by stimulated emission of radiation.

WEBThe extension of maser techniques to the infrared and optical region is considered. It is shown that by using a resonant cavity of centimeter dimensions, having many resonant modes, maser oscillation at these wavelengths can be achieved by pumping with reasonable amounts of incoherent light.

Leaping a few orders of magnitude: the optical maser
WEBYet Townes felt encouraged when he analyzed the prospects for what he decided should be called an optical maser, because it was based on the same principle as the microwave maser. The energy-level transitions that produce visible and infrared light differ from those that produce microwaves.
