Acousto-Optic Devices

A piezoelectric element is bonded to an acousto-optic medium consisting of single crystal such as tellurium dioxide (TeO2) and lead molybdate (PbMoO4) or glass, and when an electrical signal is applied to this piezoelectric element to generate acoustic waves, which are propagated in the medium, a laser beam passing through the medium is diffracted (Acousto-Optic effect).
This diffraction includes Bragg diffraction and anisotropic Bragg diffraction.
Using the former is an acousto-optic light modulator, and using the latter is an acousto-optic light deflector and acousto-optic tunable flter.
