<title>High reflectivity and fidelity SBS phase conjugation mirrors for solid state lasers</title>

In this paper, we demonstrate a (3D) analytical solution of stimulated Brillouin scattering (SBS) for high reflectivity and fidelity phase conjugation mirrors (PCM). The results are checked with experimental ones, which were obtained with CS₂ and optical fibers as nonlinear materials and high PCM reflectivities are found out. Furthermore, analytical SBS reflectivity for pumping with Gauss-Laguerre modes is demonstrated and shown to suppress high modes, when using SBS mirrors. These findings are used in some all solid-state laser (SSL) systems with SBS-PCM in order to obtain near Gaussian beams, depolarization compensation and high brightness.
