• Introduction：

Tellurium dioxide (TeO₂) crystal is a kind of excellent acousto-optic crystal material with a high-quality factor. It is widely used in acoustic-optic deflectors, acousto-optic modulators, acousto-optic harmonizers, acousto-optic filters, and tunable filters. The acousto-optic devices made of tellurium oxide have the advantages of high response speed, small driving power, high diffraction efficiency, and stable and reliable performance under the same aperture.
