21. Some technical terms for related processes include Atomic absorption spectroscopy, Compton scattering, spontaneous emission, stimulated emission . 22. The principle and concept of stimulated emission has since been extended to more devices and frequencies. 23. Stimulated emission follows the fluorescence spectrum of the molecule and is Stokes shifted relative to bleach signal.24. Examples include Vertico SMI, near field scanning optical microscopy which uses evanescent waves, and stimulated emission depletion. 25. Those photons captured may then interact with other dopant ions, and are thus amplified by stimulated emission . 26. This is not true for stimulated emission . 27. Another reasonably stable nuclear isomer ( with a half-life of 31 years ) is gamma-ray stimulated emission . 28. A : " Laser " is an acronym for " light amplification by stimulated emission of radiation ." 29. The critical detail of stimulated emission is that the induced photon has the same frequency and optical resonator. 30. Kopfermann investigated dispersion and stimulated emission .
