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.

Physics - Invention of the Maser and Laser
WebJan 27, 2005 · Charles Townes and his colleagues were the first to build a “maser,” which operated in the microwave frequency range. It was the precursor of the laser. In honor of the World Year of Physics, which commemorates Einstein’s “miraculous year” in 1905, we’re presenting papers from the Physical Review archive related to Einstein’s ...
Masers | Center for Astrophysics | Harvard & Smithsonian
WebMasers. When light in the microwave part of the spectrum shines on gas, sometimes the molecules respond by amplifying it, producing a dramatically brighter object called a “maser”. Naturally-occurring masers are found near stars and supermassive black holes, as well as in the atmospheres of Jupiter and other Solar System objects.
