TeO2 crystal is a kind of acoustooptic material with high quality factor. It has good birefringence and optical rotation performance, and the speed of sound propagating along the direction of  is slow; if the resolution of the acoustooptic device made of TeO2 single crystal can be improved by an order of magnitude under the same aperture, the response speed is fast, the driving power is small, the diffraction efficiency is high, and the performance is stable and reliable.
