Abstract

In this paper, a computer-aided simulation of the relation between peak phase delay and laser
intensity ,at different values of the Klein-Cook parameter of the fourth order diffraction, was
presented. The numerical results describing the sound-light interaction in LiNbO3 crystal with
and without feedback were presented and discussed. Also, the relations between laser
intensities and the acousto-optic frequency and the values of Klein-Cook parameter were
studied. The results were applied to an optical bistable device using MATLAB software.
