摘要：
We present an experimental study of phase-conjugation Nd:YAG laser oscillators, using a stimulated Brillouin scattering mirror. Depending upon the cavity configuration, Q-switching is provided either by a nonlinear acetate sheet before the stimulated Brillouin scattering takes place or self-starts within the Brillouin cell with no need for any further shutter. In both cases, employing proper mode selectors, pulses of near diffraction-limited divergence, energies from 10 to over 150 mJ, and durations of 10 to 20 ns were generated. A simple model of the self-Q-switching dynamics is also presented.
