摘要
非线性光学晶体是非线性光学频率变换技术中的核心器件。近些年,为进一步提高基于非线性光学频率变换技术产生太赫兹波的输出能量、转换效率,拓宽产生太赫兹波的带宽,多种新型有机晶体得以发展,并凭借其更加出色的非线性光学性质,成为产生太赫兹波的理想材料。本文按照晶体类型介绍了目前可产生THz波的多种有机晶体的性质,并总结了基于多种有机晶体的超宽带太赫兹辐射源的国内外研究进展,同时结合THz光谱检测技术的应用需求分析了基于有机晶体宽带THz辐射源的发展趋势以及所面临的关键科学问题。
Nonlinear optical(NLO)crystals are the determinant in nonlinear optics.Recently,a variety of new organic crystals have been developed to further improve the output energy and conversion efficiency and to broaden the bandwidth of THz waves based on nonlinear optical frequency conversion technology.These crystals have become an ideal material for generating THz waves with their excellent performance in nonlinear optics.In this paper,the properties of different organic crystals are introduced in the classification of ionic crystals and nonionic molecular crystals,and the progress of THz sources that use the different organic crystals are summarized.At the same time,the applications and the trends in the development of broadband THz radiation using organic crystals are analyzed.
