Abstract
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.
Claims2
An acousto-optic device comprising a single crystal of pure or mixed univalent mercury halide formed in the shape of a parallelepiped having a first face provided with a source of acoustic wave, and a pair of opposite faces polished for the entrance and exit of light waves, said first face being perpendicular to the direction [A], said direction [A] being inclined from the crystallographic direction [110] about the crystallographic direction [110] by an angle .alpha. said crystal being simultaneously inclined from the crystallographic direction [110] about the direction [A] by an angle .beta. so that the edge formerly parallel to the [110] direction points in the direction [B] and two opposite faces are simultaneously parallel to the directions [A] and [B].
