Tellurium Dioxide (TeO2, Paratellurite) is an excellent acousto-optic crystal material, it is widely applied in the production of Acousto-optic modulator (AOM), Acousto-optical deflector (AOD), Acousto-optical tunable filter (AOTF), Laser Q-switches, RF spectrum analyzers in laser technology science and optoelectronic technology, because of its high figure of merit ,which depended on high elastic coefficient and high refractive index. TeO2 acousto-optic deflectors are more suitable for acousto-optic effects with high diffraction efficiency, long bandwidth and high beam deflection speed. TeO2 has been widely used to fabricate anomalous acousto-optic devices.
There are broad applications of TeO2 crystals. These crystals can be used in the field of astronomy, laser publishing, laser recorder and so on.
We can provide TeO2 crystals with customized shapes and sizes on all directions (110), (1-10), (001). Cylinder or cube shaped crystals are available. Please contact us for custom-made TeO2 crystals for your specific application.
