Description

TeO2 Piezo-Electrical Crystal is an excellent acousto-optic (AO) crystal. It offers a high AO figure of merit, birefringence, good optical rotation, and slow propagation velocity along the [110] direction. The material is tellurium dioxide.

TeO2 Piezo-Electrical Crystal AO performance

Slow acoustic velocity along [110] is the key: it stretches the interaction time between sound and light. High figure of merit means strong diffraction per watt of RF. Good optical rotation and birefringence add design freedom. Birefringence enables polarization-based device designs. Low acoustic velocity keeps device dimensions compact.

TeO2 Piezo-Electrical Crystal material properties

The crystal starts as yellow and white fine crystalline powder. When heated, it melts to a dark yellow. It is not water soluble. Melting point is 733 C; boiling point is 1260 C. The insoluble nature simplifies wet processing. Standard crystal growth and handling apply without special precautions.

Typical applications

Preparation for AO rotators, modulators, resonators, tuning filters, and other AO devices. Astronomy, remote sensing, and laser recording. Remote sensing systems use AO tunable filters for wavelength selection. For a piezoelectric alternative, see our LiTaO3 Piezo-Electrical Crystal.
