Abstract
An acousto-optic filter utilizing the far-off-axis anisotropic Bragg diffraction comprising an optically anisotropic acousto-optic medium embodied by paratellurite. The light entrance surface is slanted to the crystalline axis to make a light beam incident perpendicularly to the surface. The light exit surface is slanted to the direction of the entrance surface to minimize the dispersion of diffracted angle due to light wave length.
