Abstract: | Based on a developed and experimentally tested model, self-oscillatory lasing regimes have been studied for a Class A four-frequency
gas ring laser with linear coupling of elliptically polarized counter-propagating waves. In the self-oscillatory regime, switching
of the intensities, polarization states, and phase differences of the counter-propagating waves is observed, and also a polarization-phase
dynamics effect involving displacement of the intensity switching point (with respect to detuning), due to the phase shift
as a result of an ellipticity different from zero.
