Abstract
An acousto-optic filter utilizing the far-off-axis anisotropic Bragg diffraction comprising an optically anisotropic acousto-optic medium embodied by a paratellurite crystal. An ultrasonic wave generated by a transducer is propagated in a direction different from that of the wave front normal to make the light-sound interaction length in the medium elongate by slanting the bonding surface of the transducer to the crystal medium.
