Аннотация: An analysis is performed of operating modes of a laser with an intracavity element which provides for feedback by the emission beam structure. It is shown that regions of two-valued solutions and hysteresis loops by the pump current are formed at the nonlinearity of the self-focusing type. Necessary conditions are determined for realization of self-stabilization of lasing parameters, self-oscillations with the period in the order of nonlinearity relaxation time.An analysis is made of the conditions of operation of a laser with an intracavity element ensuring feedback in respect of the structure of the output beam. It is shown that in the case of a self-focusing nonlinearity there are regions with double-valued solutions and hysteresis loops of the current supplying a flashlamp. The necessary conditions for self-stabilization of the lasing parameters and for spontaneous oscillations with a period of the order of the nonlinearity relaxation time are determined
