Paper Abstract

We report a widely tunable terahertz source by using QPM-GaAs crystals pumped by a near-degenerate dual-wavelength KTP OPO around 2.127μm, based on difference frequency generation (DFG). The tunable THz radiation from 0.06 THz to 3.34 THz has been achieved in QPM-GaAs crystal with coherence length of 650 μm. The maximum output THz energy is 45 nJ with the peak power of 10 W at 1.68 THz, corresponding to the energy conversion efficiency of 5×10-6 and the photon conversion efficiency of about 0.08%.
