One of these devices uses the neodymium ion to dope a YAG host crystal. Optical tweezers operate from the force created by these devices, which were used to cool rubidium-87 atoms in the creation of the first Bose-Einstein condensate. Q-switching in these devices causes a phenomenon in which the number of particles in an excited state exceeds the number in a lower energy state, called population inversion. The gain medium of these devices provides energy during pumping, and the optical cavity consists of a pair of mirrors that allows the escape of photons. For 10 points, name these devices that make light coherent through stimulated emission of radiation.
