  • 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.
