Stimulated emission is the process that gives the laser its special properties as an optical source. In this process, an incoming photon stimulates an excited atom or molecule to drop to a lower energy state, emitting a second photon that is coherent with the first. This leads to the amplification of light and the production of a coherent, monochromatic beam characteristic of lasers.
