Abstract :
A new procedure is given for calculating the Bragg angles for anisotropic acousto-optic interaction configurations where the optical axis is arbitrarily offset with respect to the interaction plane and the acoustic wave propagates perpendicular to the optical axis. Analytic expressions are given for the Bragg angles and the acoustic cutoff frequencies as a function of the offset angle.
