We present three novel phase-conjugate laser systems. A Nd, Cr:GSGG laser with a stimulated-Brillouin-scattering (SBS) mirror and plasma shutter has been investigated. A combined effect of SBS and optical breakdown allows us to control pulse duration in a wide range. A description of a Nd:YAG laser with a peak power of 1 GW in a 1-nsec pulse, achieved by means of SBS compression in CCI4, is given. A laser oscillator design with a SBS mirror arranged outside the main resonator has been studied experimentally. Nd:YA1O3 and Nd, Cr:GSGG lasers based on this design revealed efficient generation of near-diffraction-limited output.
