Exempel på hur man kan använda MASER i en mening

• A maser is a device that produces coherent electromagnetic waves (microwaves), through amplification by stimulated emission.
• For an electromagnetic wave, the coherence time is the time over which a propagating wave (especially a laser or maser beam) may be considered coherent, meaning that its phase is, on average, predictable.
• For radiation emitted by a non-thermal source such as a pulsar, synchrotron, maser, or a laser, the brightness temperature may be far higher than the actual temperature of the source.
• Coherence time, the time over which a propagating wave (especially a laser or maser beam) may be considered coherent; the time interval within which its phase is, on average, predictable.
• Maiman had begun conceptualizing a solid-state laser design even before he undertook the maser project at Hughes.
• In 1951, Townes conceived a new way to create intense, precise beams of coherent radiation, for which he invented the acronym maser (for Microwave Amplification by Stimulated Emission of Radiation).
• His central insight was the use of two mirrors as the resonant cavity to take maser action from microwaves to visible wavelengths.
• In a microwave frequency mixer, one-half of the two-way Doppler shift from the transponded ground maser signal was subtracted from the Doppler shift of the space maser.
• In 1956, Gould proposed using optical pumping to excite a maser, and discussed this idea with the maser's inventor Charles Townes, who was also a professor at Columbia and later won the 1964 Nobel prize for his work on the maser and the laser.
• In the West Germanic languages it is found as Old Saxon masur ('swelling') and Old High German masar ('knot or swelling of a tree'), and later in the Middle Ages as Middle Dutch māser ('knot or swelling of a tree', especially a maple), Middle Low German māser ('curly-grained wood'), Middle High German maser ('curly-grained wood, excrescence on the maple and other trees, drinking cup made of curly-grained wood').
• If confirmed such a planetary object could likely be an evaporating planet, with a long comet-like trail as hinted by intense SiO maser emissions.
• Among these instabilities, the firehose instability can arise due to the anisotropic pressure, and electron cyclotron maser due to population inversion in the rings.
• According to its original plan, QZSS was to carry two types of space-borne atomic clocks; a hydrogen maser and a rubidium (Rb) atomic clock.
• Some astrophysicists use the term iraser to describe a maser emitting at a wavelength of a few micrometres, even though the optics community terms similar sources lasers.
• Likewise, the term kilomaser is used to describe masers outside the Milky Way that have luminosities of order , or thousands of times stronger than the average maser in the Milky Way, gigamaser is used to describe masers billions of times stronger than the average maser in the Milky Way, and extragalactic maser encompasses all masers found outside the Milky Way.
• The payload actually contains two clocks: a caesium laser cooled atomic clock (PHARAO) developed by CNES, France for long-term stability and an active hydrogen maser (SHM) developed by Spectratime, Switzerland for short-term stability.
• In a hydrogen maser clock the gas emits microwaves (the gas mases) on a hyperfine transition, the field in the cavity oscillates, and the cavity is tuned for maximum microwave amplitude.
• The transmitters used Klystron power amplifiers, and the receivers were cryogenically cooled maser devices.
• An OH/IR star is an asymptotic giant branch (AGB) or a red supergiant or hypergiant (RSG or RHG) star that shows strong OH maser emission and is unusually bright at near-infrared wavelengths.
