ABSTRACT:
Single crystals of Tl.sub.3 VS.sub.4 and Tl.sub.3 NbS.sub.4 are disclosed which have useful acousto-optical properties, including low acoustic velocities and high acousto-optical figure of merit. They are used in acousto-optical devices such as a display device, a laser modulator, a non-collinear tunable filter, and an acousto-optical delay line.
