Paper Abstract

Since Zel' dovich discovered the phase conjugate character or stimulated Brillouin scattering (SBS), there has been considerable interest in using phase conjugation to improve the beam quality of high power laser. In this paper we report our investigation of the Nd:YAG laser oscillator with a SBS cell filled with high pressure gas SF6 as the SBS nonlinear medium. The SBS cell acts at the same time as the phase conjugating mirror and as the Q-switch because of its intensity dependent reflectivity. As a result laser pulses with the energy of 100 mJ and the duration of 10 - 25 ns per pulse have been obtained. The beam profile is nearly TEM00-mode.
