TeO2 acousto-optical crystals
Laser quality Tellurium Dioxide (TeO2 or Paratellurite) is an excellent piezo-optical material. It is extensively used because of it's high acousto-optical figure of merit in making acousto-optical modulators, imaging devices, splitters, deflectors, tunable polarisation filters, radio frequency spectral analysers and other acousto-optoelectronic equipment for laser radiation control. TeO2 crystals are grown by the Czochralsky method. It has higher damage threshold and better optical quality if compared with TeO2 crystals grown by some other methods.
