Spontaneous emission is a quantum mechanical process where an excited electron in an atom or molecule loses energy by emitting a photon, transitioning to a lower energy state without any external influence. This fundamental process underlies the operation of lasers and is a primary mechanism by which stars and other luminous bodies emit light.
