Stimulated and emission
Stimulated emission was a theoretical discovery by Einstein within the framework of quantum mechanics, wherein the emission is described in terms of photons that are the quanta of the EM field.
Stimulated emission can also be described classically however, without reference to either photons, or the quantum-mechanics of matter.
Stimulated emission can be modelled mathematically by considering an atom that may be in one of two electronic energy states, a lower level state ( possibly the ground state ) ( 1 ) and an excited state ( 2 ), with energies E < sub > 1 </ sub > and E < sub > 2 </ sub > respectively.
Stimulated emission depletion is a simple example of how higher resolution surpassing the diffraction limit is possible, but it has major limitations.

Stimulated emission ( also known as induced emission ) is the process by which an electron is induced to jump from a higher energy level to a lower one by the presence of electromagnetic radiation at ( or near ) the frequency of the transition.
