Abstract

Fast-flow lasers with controllable dynamical regimes were analyzed. Generator-amplifier resonator system considered in the paper was found to possess particular physical mechanism of self-modulated pulsing. The mechanisms lie in the generator and amplifier interaction due to the feedback supplied with the flow. One of the mechanisms is the inversion saturation in the amplifier, which determines the gain of the medium entering the generator. At the same time spatial modulation of the gain profile, as a result of the edge effects in non-stationary optical field, can also affect the regime of lasing. Methods of a regime control based on mechanisms mentioned above are proposed.
