Аннотация:It is shown with the help of numerical simulation that various mechanisms of self-oscillation instability exist and self-oscillation perturbations of various types may appear in an unstable resonator with a transverse flow of the active medium and a nonuniform internal pumping. The interaction of different self-oscillation perturbations, manifested in pulling and locking of oscillation frequencies and a variation of their increments, is studied. Analytic relations describing the spatial structure of perturbation modes and used for evaluating their frequencies and increments from steady-state generation parameters are presented.
