Abstract

The collinear phase-matched THz-wave generation in GaP crystal was discussed using collinear difference frequency mixing. The phase-matching conditions were calculated by determining the wavelength range and length of GaP crystal for efficient difference frequency generation (DFG). THz waves were generated using a dual-wavelength KTiOPO4-Optical parametric oscillator (KTP-OPO) from 0.5 to 4.5 THz by angle tuning the KTP crystal in the OPO cavity. It was found that tunable THz-wave system, consisting of a DFG-based THz-wave source and a pyroelectric detector was useful in practical THz imaging, THz sensing and spectroscopic applications.
