MSE PRO™ Tellurium Dioxide (TeO₂) Single Crystal Substrates

Tellurium Dioxide, TeO₂ is an excellent ascousto-optic (AO) crystal with high AO figure of merit, birefringence, good optical rotation, and slow propagation velocity along [110] direction. The resolution of AO devices made of TeO₂ crystals will increase several levels above others. It is an ideal single crystal material for preparation of AO rotators, modulators, resonators, tuning filters and other AO 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 dimensions on all directions (110), (1-10), (001), (111), (100). Cylinder or cube shaped crystals are available. Please contact us for custom-made TeO₂ crystals for your specific application.
