Maser meaning

māzər
Frequency:
The maser is a device similar to the laser, but emitting microwave radio waves rather than light. In 1953, Charles H. Townes, James P. Gordon, and Herbert J. Zeiger invented the maser, which earned them the Nobel Prize in Physics in 1964. Research continued into the 1950s, leading to the optical maser, or laser, for which AT&T Bell Telephone Laboratories was awarded a patent in 1960. See also laser.

Short for microwave amplification by stimulated emission of radiation. A device that generates coherent microwaves using the same principles as a laser . Masers are used in a variety of applications, including in atomic clocks . Natural masers are found in outer space when water or other substances are excited by radiation from a star or by the energy of a collision.
