Spontaneous Emission

A quantum effect causing the spontaneous decay of excited states of atoms or ions.

Spontaneous emission is when an atom or a Laser ION in a Gain medium is excited into a higher-lying Energy level by Absorption of a photon, it may after some time spontaneously return to its Ground state, or to some intermediate Energy Level by releasing the energy in the form of a photon which carries the energy in some random direction.
