Abstract

Widely tunable THz-wave generation with thin organic crystal 4-N,N-dimethylamino-4′-N′-methyl-stilbazolium tosylate (DAST) was demonstrated. The pump source for optical parametric oscillator was a 532 nm Q-switched Nd:YAG/second harmonic generation laser, with a pulse duration of 8 ns and 20 Hz repetition rate. A continuously tunable THz-wave was successfully generated in the range of 1.5 to 6.5 THz with 0.2 and 0.3 mm thick DAST crystals. The maximum output was obtained at 2.5 THz and the peak output power was about 10 mW.
