中红外波段二阶非线性光学晶体材料研究进展

新型无机红外波段二阶非线性光学晶体材料在光电子领域有着重要的应用，对它们的探索是当前非线性光学材料研究领域的难点和前沿方向之一。本文将材料按组成分成三大类（即经典的ABC₂型黄铜矿结构化合物，硫属元素其他化合物和AMX₃型卤化物），分别就新材料探索、已知材料的单晶生长等综述了近10余年来中红外波段二阶非线性光学晶体材料的研究进展。

Progress of Second-order Nonlinear Optical Crystals in the Mid-infrared Region

Search for new inorganic second harmonic generation materials that can be used in mid-IR region is one of the current frontier topics in the field of the nonlinear optical materials. This paper reviews the progress on the materials in the past two decades, including the search for new materials and improvement of crystal quality of the known materials. The materials are divided into three catagories: i.e. the classic ABC₂ type chalcopyrites, the other sulfur family compounds, and AMX₃ type halides.
