摘要：

Among nonlinear materials, the organic ionic salt crystal 4-dimethylamino-N-methyl-4-stilbazolium-tosylate (DAST) is known for its large nonlinearity. We generated a coherent terahertz (THz) wave,using DAST, from the difference frequency between two oscillating wavelengths of an electronically tuned Ti:sapphire laser. In LiNbO3, LiTaO3, KTiOPO4, and GaP crystals, THz-wave generation was not observed under the same experimental conditions. This result proves the high efficiency of DAST crystals for generation of difference-frequency THz waves. (C) 1999 Optical Society of America.
