Here a large deflection angle, low optical frequency-shift acousto-optic device is presented. This is realized by two successive acousto-optic interactions in the same cell. The relevant parameters of operation are analyzed in detail. A practical case with paratellurite material is then considered. Results from numerical computations leading to practical design parameters are given and compared with experimental ones.
