10-W single-rod Nd:YAG laser with stimulated Brillouin scattering Q-switching mirror

Abstract

A Nd:YAG laser with a phase-conjugating mirror based on stimulated Brillouin scattering in a SF(6) cell is described. The output energy was up to 300 mJ in 15-ns pulses with shot-to-shot fluctuations of less than 3%. The repetition rate could be varied between 15 and 45 Hz without changes in the spatial-beam profile, which was close to a TEM(00) mode.
