A 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. Townes , James P. Gordon , and Herbert J. Zeiger at Columbia University in Masers are also used as the timekeeping device in atomic clocks , and as extremely low-noise microwave amplifiers in radio telescopes and deep-space spacecraft communication ground stations. Modern masers can be designed to generate electromagnetic waves at not only microwave frequencies but also radio and infrared frequencies.

Electrons absorb an electric current or electromagnetic wave and become excited, which means they jump from a low energy state to a higher energy state. Then, when they drop back down into the lower energy state, the energy they must release to do so is released in the form of a photon. The photon's given off from electron's this way are all the same wavelength, and are focused in the same direction. The difference between a laser and a maser is that the photon from a laser comes in the form of visible light , while a photon from a maser comes in the form of a microwave. How do masers work compared to a laser? Solace M. May 29,

Physical Review. Extremely powerful masers, associated with active galactic nuclei , are known as megamasers and are up to a million times more powerful than stellar masers.

Since ancient times, people believed that rays of light carry grand and mysterious powers. Interest in radiation redoubled around the start of the 20th century with the discovery of radio, X-rays and radioactivity. A whole spectrum of radiation opened up, with wavelengths longer or shorter than light.

Device for producing coherent EM waves in the sub-visible spectrum. Okuma56 New member Getting Addicted Newbie. You should upgrade or use an alternative browser. The maser is based on the principle of stimulated emission proposed by Albert Einstein in ISBN A maser is a device that produces coherent electromagnetic waves microwaves , through amplification by stimulated emission. She's still going, does anyone have anything updated? Maser-like stimulated emission has also been observed in nature from interstellar space , and it is frequently called "superradiant emission" to distinguish it from laboratory masers.
