Self-Starting Solid-State Laser with Dynamic Self-Adaptive Cavity

摘要

This report results from a contract tasking Institute of Applied Physics as follows: The present project is directed at the development of physical principles of creation of solid-state lasers of a new class with cavity completed by dynamic holographic gratings induced in nonlinear medium by generating beam itself. The self-starting laser oscillator based on Nd:YAG laser crystals with cavity formed with participation of refractive-index and gain gratings accompanied by population gratings induced in the laser crystal by generating waves will be studied both experimentally and theoretically. The industry-related importance of our project is indicated in its main goal: the solution of a very important problem of laser engineering, - that is the creation of a high power industrial laser with good beam quality. Such lasers could find numerous applications in precision technologies such as drilling of small apertures, cutting, spot thermo-hardening of metals, treatment of ceramics and other materials.
