amplified stimulated emission
1Self-Amplified Stimulated-Emission — Self Amplified Spontaneous (or Stimulated) Emission (SASE) is a process within a Free electron laser (FEL) by which a laser beam is created by the high energy electron beam. The lasing starts up from the random microbunching (i.e., shot noise) on …
2Amplified spontaneous emission — (ASE) or superluminescence is light, produced by spontaneous emission, that has been optically amplified by the process of stimulated emission in a gain medium.Origins and problemsASE is produced when a laser gain medium is pumped to produce a… …
3Induced gamma emission — In physics, induced gamma emission (IGE) refers to the process of fluorescent emission of gamma rays from excited nuclei, usually involving a specific nuclear isomer. It is analogous to conventional fluorescence, which is defined to be the… …

7Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …

9Megamaser — A megamaser is a type of astrophysical maser, which is a naturally occurring source of stimulated spectral line emission. Megamasers are distinguished from astrophysical masers by their large isotropic luminosity. Megamasers produce roughly 103… …
10Astrophysical maser — An astrophysical maser is a naturally occurring source of stimulated spectral line emission, typically in the microwave portion of the electromagnetic spectrum. This emission may arise in molecular clouds, comets, planetary atmospheres, stellar… …
