Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2. Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2.

Brief2: TeO2 crystal is a kind of acousto-optic material with high quality factor. T、there are good birefringence and optical rotatory properties, and the velocity of propagation is slow along [110].If under the same clear aperture, use TeO2 single crystal made the resolution of the acousto-optic device can increases the order of magnitude, the response speed, driving power is small, high diffraction efficiency, stable and reliable performance, etc.
