137 - Stimulate Emission
In this video Paul Andersen explains how stimulated emission can be used to create coherent light. When an atom absorbs a photon it moves to a higher energy level through stimulated absorption. It may then release a photon and moves to a lower energy level through spontaneous emission. However a stimulated atom at a high energy level may release to identical photons that travel coherently. An example of stimulated emission can be found in a laser.
