Product Details
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 deflector(AOD), 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. TeO2has been widely used to fabricate anomalous acousto-optic devices.
