ABSTRACT:
Crystals formed of Tl.sub.3 AsS.sub.3 provide very good materials for the nonlinear optical conversion efficiency. The crystals are useful in nonlinear optical devices such as harmonic generators and optical parametric oscillators, and in linear applications such as acousto-optical devices. The method of preparing such crystals is also disclosed.
