Paper Abstract

We present a self-starting Nd:YAG laser-oscillator with cavity formed by refractive index gratings and gain gratings accompanying population gratings which are induced in the laser crystal by generating beams themselves. The spatio- temporal and spectral characteristics of the laser including two Nd:YAG-amplifiers, a saturable absorber and a Sagnac interferometer are investigated. The laser-oscillator with a nonlinear mirror has displayed self-adaptivity to strong thermally induced intracavity distortions. Generation of single mode beams with up to 60 W average power and near- diffraction limited quality has been achieved.
