Lasers can be made to oscillate simultaneously at two frequencies by means of anisotropic or nonreciprocal resonator elements. A technique is described for stabilizing the resulting frequency separation by locking it to an external frequency source. The stabilized separation should be useful in optical heterodyne applications.
