For stimulated emission
properties, input-output intensity dependence, peak emission wavelength versus input intensity, and the spectral width versus input intensity have been presented.
Let P03 be the pumping rate from state 0 to excited state 3, P30 and P31 be the stimulated emission
rate from excited state 3 to state 0 and state 1 respectively.
The pertinent state transition is that of stimulated emission
, i.e., the optically induced transition from the excited to the ground state.
It can be seen from  that all wavelengths in the probe signal are equally amplified through the stimulated emission
, demonstrating the broadband performance of the loss compensation subject.
A laser is a device that emits electromagnetic radiation via stimulated emission
. Theodore Maiman developed the first laser (a ruby laser).
Once on the ES, carriers can relax on the twofold GS within a period of time [[tau].sup.ES.sub.GSn] , they can be thermally reemitted in the WL reservoir [[tau].sup.ES.sub.WLn] or recombine spontaneously with a spontaneous emission time [[tau].sup.spon.sub.ES] or by stimulated emission
of photons with ES resonance energy.
Laser is an acronym for light amplification by stimulated emission
Few laypeople, perhaps, know the term "light amplification by stimulated emission
of radiation", although everyone knows the technology by its familiar name.
This "stimulated emission
" meets the definition of a laser (Light Amplification by the Stimulated Emission
p.126 The paragraph about 'modern science' refers (unnecessarily) to Einstein's theory of stimulated emission
, and the sentence about quantum physics is mixed up.
In general, LA-SER is an acronym of Light Amplification by Stimulated Emission
of Radiation, which is light with a high power concentrated in a focused area, i.e.
Laser stands for Light Amplification by Stimulated Emission
