A third type of photon-related electron transitions in an atom is stimulated emission. Suppose an electron is in a higher energy level and a photon comes along with an energy equal to the difference between the electron's energy and a lower energy.

Transitions between these quantized states occur by the photon processes absorption, emission, and stimulated emission. All of these processes require that the photon energy given by the Planck relationship is equal to the energy separation of the participating pair of quantum energy states.

; Incident photon interacts with an excited electron and loses its energy by emission of a photon of identical phase direction and energy.

Phase Shifts in Stimulated Emission ... But, in addition to establishing the existence of the process of stimulated emission, Einstein also asserts that the radiation produced in stimulated emission is identical in all relevant aspects to the incident radiation.

Normally the atom will emit its photon very quickly (in less than 10−6 s) and at random (spontaneous emission), but if a photon of the same wavelength passes while the atom is still in an excited state the atom will emit its photon in phase with the passing photon (stimulated emission).
