TeO₂ is an excellent acousto-optic (A-O) crystal with high AO figure of merit, larger birefringence, good optical rotation and slow propagation velocity along [110] direction. The solution of A-O devices made of TeO₂ crystals will promote performance several levels than others. It is an ideal single crystal material for preparation of Acousto-Optic Rotators, Modulators, Resonators, Tuning Filters and other A-O devices.
U-Optics can provide TeO₂ single crystal with size as large as 120mm x 80mm x 40mm on all direction, as well as cylinder or cuboid shape single crystals.
