摘要：

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 spatiotemporal 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.
