SELF-MODELOCKING OF CW SOLID-STATE LASERS WITH NONLINEAR BIREFRINGENTPOLARIZATION MODULATOR

The possibility of effective self-modelocking is shown for cw solid-st ate lasers with two types of nonlinear birefringent polarization modul ators on the basis of fluctuation model. Discriminative performance of the modulators is based on utilyzing of the intensity dependent rotat ion and distortion of the polarization ellipse of the radiation propag ating in birefringent medium due to self-phase modulation of the two p olarization components. The linear phase mismatching of the components and angular orientations of modulator elements are founded for which the modulators possess the discriminative properties. The analysis of the cw laser parameter ranges of effective self-modelocking due to non linear birefringent modulators is performed.
