Abstract

We present a numerical and experimental study of a self-Q-switching phase-conjugation Nd:YAG laser oscillator with a stimulated-Brillouin-scattering mirror. Q-switching is provided only by a nonlinear liquid in the cavity without further need for any shutter. During the stimulated-Brillouin-scattering process, through switching by intracavity radiation, laser beam spot-size widening occurs because of imperfect phase conjugation. It is demonstrated that the results of numerical simulation of the intracavity photon number, pulse duration, and laser beam spot size at the output coupling mirror for the laser are comparable with those observed experimentally.
