DEPENDENCE OF THE FREQUENCY OF LOW-FREQUENCY RELAXATION OSCILLATIONS OF A SOLID-STATE RING LASER ON THE POLARIZATION

An investigation is reported of the dependence of the frequency of low -frequency relaxation oscillations of the output power of solid-state ring lasers on the nature of the polarisation of the counterpropagatin g optical waves and on the ring cavity parameters, It is shown that th e maximum frequency of antiphase low-frequency oscillations correspond s to the linear collinearly oriented polarisations of the counterpropa gating waves, An increase in the ellipticity of the counterpropagating waves reduces the frequency of the antiphase oscillations and this fr equency tends to zero for orthogonal circular polarisations of these w aves.
