We discuss the design and performance of a master oscillator/regenerative power amplifier laser system using a stimulated Brillouin scattering phase conjugator to control beam aberrations within the amplifier cavity. The master oscillator is a self-seeded Q- switched Nd:YLF laser which provides up to 40 mJ of single frequency light in a 10 ns to 15 ns pulse for amplification. The power amplifier uses a regenerative ring design with approximately 10 total passes and a phase conjugate mirror after the 5th pass. The conjugator is necessary to help produce a plane wavefront and thus a uniform intensity distribution within the ring, a requirement to avoid damage at the high intensities. The energy at the phase conjugate mirror exceeds 1 J/pulse and thus careful attention is paid to the tradeoff between input energy, conjugator reflectivity and near field spatial fidelity of the return. The laser output is in the range of 20 J/pulse, 2 GW peak with average power of 70 W. Measurements have been made at high power of the near field and far field beam quality.
