Deflection of an injection laser beam by an acousto-optic deflector

It is shown experimentally that an injection laser beam can be deflected quite effectively by an acoustooptic deflector. The maximum deflection obtained (~40') corresponds, for the divergence of the investigated beam, to 8 resolvable positions a hologram memory. A deflection by ~6° is possible if an ultrasonic cell contains a TeO₂ crystal.
