Abstract

Ring gas lasers (RGL) with anisotropic cavities represent an appropriate model to study polarization dynamics in multi - mode systems, because even in the case of single-longitudinal-mode operation there are four waves above the threshold with different intensities, frequencies and states of polarization [1-3]. Another factor which is inherent in RGL (unlike standing-wave ones) is the determining role of the phase characteristics of the emitted field on laser operation.
