New principles of distributed feedback lasers with cavity formed by refractive index gratings induced in the laser crystal by generating beams themselves have been discussed. Different geometries of the cavity (linear, loop and multi- loop) with Nd:YAG crystal have been investigated experimentally. The oscillator with a nonlinear mirror has displayed self-adaptivity to strong intracavity distortions. Generation of single transverse mode beams with near- diffraction limited quality in millisecond pulse-repetitive regime with 12 W average power has been achieved in the oscillator with single Nd:YAG amplifier.
