Abstract

We report Q-switching of a Nd:YAG laser with a phase-conjugating mirror based on external stimulated Brillouin scattering in carbon disulfide using a linear resonator. Q-switching is provided by a nonlinear LiF:F₂^- crystal before the stimulated Brillouin scattering takes place. Employing proper mode selectors pulses with 6 mJ minimum energy and duration of 20 ns were generated, the beam divergence being 1.5 the diffraction limit. A new theoretical model of the Q-switching regime has been proposed and good agreement between experimental and theoretical data has been obtained.
