    TeO2is an excellent acousto-optic media because of its high AO figure of merit, larger birefringence, optical rotation and slow propagation velocity along [110] direction. The solution of AO devices made of TeO2crystal, like AO Rotators, Modulators, Q-Switch, Resonators, Tuning Filters …, features much powerful performance than other AO medias.
