Paper Abstract

Recently, we grew organic ionic-salt crystals of 4- dimethylamino-N-methyl-4-stilbazolium-tosylate (DAST) with extremely large nonlinearity, and also realized dual wavelength oscillation of an electronically tuned Ti:Sapphire laser. In this report, the generation of a coherent THz-wave from DAST crystal was demonstrated for the first time by the difference frequency generation of a dual- wavelength oscillating Ti:Sapphire laser.
