TeO2 is an excellent acousto-optic (AO) crystal with high AO figure of merit, larger birefringence, good optical rotation and slow propagation velocity along [110] direction. The resolution of AO devices made of TeO2crystals will increase several levels than others. It is an ideal single crystal material for preparation of AO rotators, modulators, resonators, tuning filters and other AO devices. Dream Lasers can provide TeO2 crystal at size of 30 x 30 x 50mm3 on all direction, as well as cylinder or cuboid shape single crystals. The TeO2 crystal can be used in the field of astronomy, remote sensing, laser publishing, laser recorder and so on. The application filed of TeO2 crystal is huge.
