Paper Abstract

Many applications of solid state lasers in research, material processing and especially in micromachining and medicine require high brightness. Resonators for solid state lasers with phaseconjugate mirrors based on stimulated Brillouin scattering (SBS) allow significant improvement of the beam quality up to theoretical diffraction limit at high average powers. We could demonstrate operation of a flashlamp-pumped Nd:YAG laser with SBS mirror with an average output power of more than 30 W and TEMoo-mode. The beam diameter in the laser rod of 8 mm diameter was larger than 5 mm.
