This paper presents the study of the stimulated Brillouin scattering (SBS) process when the self-focusing effects of the pump and scattered laser beams are taken into account in three dimensions within the paraxial ray approximations. Integrated SBS reflectivity is found to exhibit a maximum value at an optimum SBS gain. The reflectivity with pump depletion is less than without pump depletion and several orders of magnitude lower than the usual three-wave interaction case. The effect of the statistical distribution of the laser beam on the SBS reflectivity has also been discussed.
