Abstract

A high average power laser oscillator with a cavity completed by refractive index gratings that accompany population gratings induced in Nd:YAG laser crystals by generating beams themselves is investigated experimentally. The spatio-temporal self-adaptation of the cavity formed by nonlinear dynamic mirrors is studied. The possibility of compensating polarization distortions inside laser crystals is also investigated. The generation of beams with average power up to 250W, near-diffraction-limited divergence, and long coherence length is demonstrated.
