Abstract: An analytic model for the description of the generation of ultrashort pulses in solid-state lasers having passive switches based on semiconductor absorbers, considered as nonlinear Fabry — Perot interferometers, is proposed. The possibilities of controlling the parameters of ultrashort pulses by varying the switch parameters are demonstrated. The stability of the solutions obtained is investigated.
