Temporal response of the acoustooptic modulator in the high scattering efficiency regime

An efficient and rigorous algorithm is proposed for analyzing the temporal response of the Bragg acoustooptic modulator in the high scattering efficiency regime. Computer studies of this model successfully predict pulse profile asymmetries that have been observed experimentally and cannot be predicted by the usual Green's function (small signal) models of the acoustooptic coupling. The technique of predistorting the electronic video signal by passing it through a nonlinear electronic network to linearize the modulator response is effective only for slowly varying video signals. Residual nonlinearities appear for rapidly varying video signals.
