TeO2 is a kind of acousto-optic material with high quality factor. It has good properties of birefringence and optical rotation with low velocity of propagation along (110) axis. Under the same clear aperture, the acousto-optic device produced by TeO2 crystals has the advantages of orders of magnitude improvement in resolution, fast response speed, small driving power, high diffraction efficiency, as well as stable and reliable performance.
TeO2 crystals are ideal single crystal material used to produce different kinds of acousto-optic device, such as acousto-optic deflector, modulator, resonator and tunable filter.
