Abstract
In one application, the apparatus is used with unstable laser resonators which include a gain region defined by a concave mirror and a convex mirror. The apparatus includes a spectral line selection medium, such as a multiple band pass filter or a multiple diffraction grating, which is located so that the laser beam directed out of the laser gain region impinges thereon. A retroreflector is positioned so that the spectral lines selected by the line selection medium are reflected back into the laser gain region along the propagation path of the incident beam, resulting in a lockup of the laser at the selected spectral lines.
