A phase conjugate resonator PCR using stimulated Brillouin scattering SBS was investigated. Carbon disulfide, in a waveguide tube, was used as the nonlinear medium. A collinear startup resonator was employed, and output was obtained by cavity dumping the phase conjugate resonator. The performance of the PCR was optimized through the use of various etalon elements, including resonant reflectors. Aberrators and cavity misalignment were used to test the fault tolerance of the PCR. The PCR compensated well for induced faults with respect to energy output, but beam quality was, in general, degraded with the SBS process. The large SBS frequency shift of carbon disulfide hurt the performance of the PCR.
