UNSTEADY-STATE PROCESS IN ELECTROOPTICAL CELL WITH A DELAY NEGATIVE FEEDBACK

Dynamic properties of the electrooptical cell employed in lasers with external feedback have been investigated. A spectrum of the feedback s ignal consisting of equidistant harmonics is applied to the electrodes of the cell, the spectrum being restricted by the frequency propertie s of the negative feedback circuit. The parameters of the unsteady-sta te process occurring in the cell-have been determined for the first ti me: conditions of self-excitation, damping time, period of the oscilla tory process. The conditions of stability of the negative feedback cir cuit have been studied. The stabilizing properties of the electrooptic al circuit have been estimated.
