摘要：

We investigated terahertz (THz) properties of a new organic crystal, 4'-dimethylamino-N-methyl-4-stilbazolium p-chloro-benzenesulfonate (DASC). High-quality DASC crystals were grown using a slow-cooling method in methanol solution. Tunable THz waves over a wide range of 2 to 19 THz were generated in DASC crystals by difference-frequency mixing. The highest THz energy of 520 nJ was obtained at 11.3 THz. THz properties of DASC were compared with those of the conventional 4'-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST).
