Wikipedia
A maser (, an acronym for "microwave amplification by stimulated emission of radiation") is a device that produces coherent electromagnetic waves through amplification by stimulated emission. The first maser was built by Charles H. Townes, James P. Gordon, and H. J. Zeiger at Columbia University in 1953. Townes, Nikolay Basov and Alexander Prokhorov were awarded the 1964 Nobel Prize in Physics for theoretical work leading to the maser. Masers are 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.
Contemporary masers can be designed to generate electromagnetic waves at not only microwave frequencies but also radio and infrared frequencies. For this reason Charles Townes suggested replacing "microwave" with the word "molecular" as the first word in the acronym maser.
The laser works by the same principle as the maser, and the maser was the forerunner of the laser, inspiring theoretical work by Townes and Arthur Leonard Schawlow that led to its invention in 1960. When the coherent optical oscillator was first imagined in 1957, it was originally called the "optical maser." This was ultimately changed to laser for "Light Amplification by Stimulated Emission of Radiation." Gordon Gould is credited with creating this acronym in 1957.
A maser is a device that produces coherent electromagnetic waves.
Maser may also refer to:
- Astrophysical maser, a naturally occurring source of stimulated spectral line emission
- Mike Maser, a coach for the Miami Dolphins
- Maser, Veneto, a municipality in Italy
- Maser (rocket), a sounding rocket launched from Esrange in Sweden
- Werner Maser, (1922-2007), German historian and author of books about Adolf Hitler including Hitler's Letters and Notes and Hitler: Legend, Myth and Reality
Maser is a sounding rocket that is used in the MASER microgravity research rocket programme, which is operated by the Swedish Space Corporation (SSC). The main customer is the European Space Agency ( ESA), and in particular its EMIR and ELIPS programmes.
The launches take place at Esrange in Northern Sweden. The programme offers 6-7 minutes of microgravity and full recovery of the experiment modules with helicopter immediately after flight.
