Dynamic Processes in a Collinear Acousto-Optic Generator Based on the Effect of Optical Heterodyning

The operation of an optoelectronic generator with collinear geometry of acousto-optic interaction is studied, in which the feedback signal is formed due to the effect of optical heterodyning. The process of establishing different types of oscillations depending on the feedback coefficient and the phase mismatch between interacting optical and acoustic beams is considered. The issues of possible application of such systems are discussed.
