Abstract
An acousto-optic deflector or modulator is shown which diffracts a beam of incident light from a zero order beam into a first order beam. Normally such diffraction deflects but 1% of the light energy within the incident beam. This deflection may be improved by successive transits of the light beam across the acoustic energy wave within the deflector.
