Stimulated Brillouin scattering (SBS) is a third-order nonlinear optical effect. Stimulated Brillouin scattering phase conjugate mirror (PCM) is a self pumped PCM based on SBS. SBS-PCM can compensate wavefront distortion caused by system thermal aberration and material inhomogeneity and improve laser beam quality. The applications of SBS-PCM are becoming more and more extensive. We review the typical laser configuration with SBS-PCM. Research progress in this field at home and abroad is briefly summarized. Some problems to be resolved are also put forward.
