Abstract

AgGaGeS₄compound (AGGS) is a promising nonlinear material for mid-IR applications. The different steps of this materials processing are presented. The chemical synthesis of polycrystals and the single crystal growth process are described. Compounds volatility can induce stoichiometry deviation and reduce the quality of obtained single crystals. Nevertheless, 28 mm diameter and 70 mm length single crystals have been grown by Bridgman-Stockbarger method, cut and polished AGGS crystal is obtained. The crystal has good homogeneity and absorption coefficient of less than 0.1 cm-1 in the 0.5-11.5 μm range which make it usable in nonlinear devices.
