Abstract

The results of experimental investigations of the regime of acoustic interference in acousto- optic cells for optical beam control are represented. The crystals TeO₂, LiNbO₃, Al₂O₃ and KRS-6 are used as the materials of interferometers. The forms of frequency responses of interferometers verify sharp changes of input impedance. The transitory regime of interferometer is investigated and the changing of input impedance of interferometer in transient process is shown. The extension of frequency bandwidth approximately 2 times more is observed. The gain of peak power for constructive interference was reached approximately 4 divided by 30 times for different conditions. The results of experimental investigations of quasi- collinear acousto-optic filter using degenerated shear mode in (001) direction of LiNbO₃ crystal is presented.
