stimulated emission

stimulated emission: In a quantum mechanical system, the radiation emitted when the internal energy of the system drops from an excited level (induced by the presence of radiant energy at the same frequency) to a lower level. Note: An example of stimulated emission is the radiation from an injection laser diode operated above the lasing threshold.
