Abstract: A three-dimensional mathematical model of a repetitively pulsed SBS-mirror laser is proposed, which describes the development of lasing, the interaction of counterpropagating beams in a saturated active medium, and the scattering of a focused beam in an SBS-active medium. Based on this model, the possibility of forming a laser mode of large volume with divergence close to the diffraction limit is shown. The factors that cause an increase in the transverse size of the laser mode are analysed.
