Abstract

Difference-frequency mixing was used for the generation of terahertz (THz)-waves in an organic crystal. As the input light source, a dual wavelength optical parametric oscillator (OPO) with two KTiOPO4 crystals was developed with a tunable range of 1300-1450 nm. Using the OPO, widely tunable THz waves ranging from 2 to 20 THz were generated from the organic crystals with 0.5- and 1-mm thickness. THz spectroscopic data for a PTFE sheet were obtained using a tunable THz-wave system consisting of the THz source and a pyroelectric detector.
