Radiative charge carrier recombination induced by incident photons of appropriate wavelength, which synchronize emission of other photons as to their wavelength, phase, polarization and direction of travel.
Note:
If this process takes place in a system with a high population of excited states, it leads to stimulated emission, the principle of the function of lasers.
