摘要
中、远红外波段黄铜矿类半导体晶体磷化锗锌(ZnGeP2,ZGP)非线性系数、热导率、光损伤阈值高,在中、远红外波段的频率转换方面有广阔的应用前景,特别是其非线性系数是KDP的160倍,是已知非线性光学晶体中最高者之一。该晶体的生长及其应用研究正在逐渐引起各国政府和科研人员的高度重视,并成为材料与光电子(激光)领域的研究热点之一。本文全面综述了该晶体的物性与电光性能,以及多晶原料的合成与单晶的生长方法和其应用前景。
The ternary chalcopyrite compound zinc germanium phosphide(ZnGeP_2, ZGP) has outstanding fundamental properties as a middle and far IR nonlinear crystal, such as wide optical transparent range, high thermal conductivity and optical damage resistance. In particular, the large nonlinear coefficient of ZGP, which is approximately 160 times higher than that of KDP, makes it one of the most efficient nonlinear crystals known. It has a large number of applications in frequency conversion throughout its transparent region. The optical, physical and electro-optical properties of ZGP single crystal, and its synthesis, growth and applications were described in detail.
