stimulated emission

[′stim·yə‚lād·əd i′mish·ən]
(atomic physics)
Emission of electromagnetic radiation by an atom or molecule as a result of its interaction with incident radiation of the same frequency. Also known as induced emission.
(electromagnetism)
The emission of radiation at a given frequency that results from the presence of an external radiation field of the same frequency.

On the other hand, for high current, when the current is switched off, the number of existing carriers is high enough to increase the rate of stimulated emission and as a result, the fall time decreases.
One technique merges SMI and stimulated emission depletion to yield subdiffraction imaging with a method termed nonlinear structured illumination.

I know that laser is Light Amplification of Stimulated Emission of Radiation, and most of us use it in our DVDrecorders and players, among other uses such as sight correction surgery etc.
Many years ago, when people were playing with microwaves and radar, it was discovered that it was possible to 'tune' the microwave radiation, and gadgets were invented called MASERS - 'Microwave Amplification by the Stimulated Emission of Radiation'.
The word LASER, now common, is actually an acronym for Light Amplification by Stimulated Emission of Radiation.
These crystals have a large stimulated emission cross section at laser wavelength and a high absorption coefficient and wide bandwidth at pump wavelength, but they have a low dependency on pump wavelength and produce a strongly polarized laser output.
No one will be threatening any Star Fleet officers with the device, but the uaser (from "ultrasound amplification by stimulated emission of radiation," and pronounced "WAY-zer") might someday find its way into materials research laboratories.
All that is required appears to be (1) transitions within two states, (2) absorption, (3) spontaneous emission, and (4) stimulated emission.
