Abstract

The versatility of lasers, or the fact that one can construct lasers with a wide range of properties, arises because the parameter space for lasers is very large. An interesting region of parameter space, which has largely been ignored in the past, is that of lasers with quasi-isotropic cavities and gain media. (Quasi-isotropic, since in practice, residual imperfections in all optics render any cavity slightly anisotropic.) Such lasers may be used for interferometry1, for intracavity polarimetry2, and since they exhibit a bistability3, may find applications in optical communication. We have recently developed a theory of quasi-isotropic lasers4 which is in qualitative agreement with preliminary observations5. In (4) we examined the steady-state solutions and carried out an approximate treatment of the problem of stability and hysteresis. Here we firm up the stability and hysteresis analyses and begin to extend the calculations to include the dynamics of the polarization flip.
