Description
Tellurium Dioxide (TeO2, Paratellurite) is an excellent acousto-optic crystal material, it is widely applied in the production of Acousto-optic modulator (AOM), Acousto-optical deflector (AOD), Acousto-optical tunable filter (AOTF), Laser Q-switches, RF spectrum analyzers in laser technology science and optoelectronic technology, because of its high figure of merit ,which depended on high elastic coefficient and high refractive index. TeO2 acousto-optic deflectors are more suitable for acousto-optic effects with high diffraction efficiency, long bandwidth and high beam deflection speed. TeO2 has been widely used to fabricate anomalous acousto-optic devices.
Feature
- Small sound attenuation
- Large sound and light quality factor
- High figure of merit
- Excellent sound and light characteristics
- High transparency to visible light
- High refractive index
