TeO2 Crystal Boule
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 than others. It is an ideal single crystal material for preparation of AO rotators, modulators, resonators, tuning filters and other AO devices.
