Acousto-optic device

摘要

A single crystal of pure or mixed univalent mercury halide is formed having a first face perpendicular to the direction [A] which is inclined about the crystallographic direction [110] by an angle alpha . The crystal is simultaneously inclined from the crystallographic direction [110] about the direction [A] by an angle beta so that the two opposite faces for entrance and exit of the light wave are parallel to the direction [A] and [B]. The first face of the parallelepiped is provided with an acoustic wave.
