Image:Stimulated emission (laser)

Description: Illustration showing an excited electron in an elevated state circling the nucleus, and emitting a photon. In a laser, this process is triggered by an incoming photon, and the emitted photon matches the phase and direction of the incoming photon, leading to the formation of a laser beam where all the photons are exactly in phase.
