Abstract: We study experimentally stimulated Brilluoin scattering (SBS) of vortex laser beams, namely, the LG₁¹ and LG₀¹ Laguerre -Gaussian modes. The wave front transformation is experimentally demonstrated in the case of SBS of the LG₁¹ laser mode, directly focused into the SBS cell, when the fundamental Gaussian mode LG₀⁰ rather than the conjugate mode is selected from the Stokes beam. It is shown that optical vortices become phase conjugate by destroying the laser mode structure in the SBS cell. Phase conjugation (PC) of the LG₀¹ and LG₁¹ modes is obtained in the SBS mirror using a regular aberrator (microlens raster) in the system of laser beam focusing into the SBS cell.
