Abstract:

Tunable terahertz THz-wave generation has been achieved by difference frequency generation DFG in a GaP crystal, with a KTiOPO4 KTP optical parametric oscillator OPO. We have developed a dual signal-wave OPO with two KTP crystals of phi 55 degrees to oscillate wavelengths from 980 nm to 990 nm, corresponding to the phase matching wavelength for DFG in GaP. Continuously tunable THz-waves were successfully generated in the 0.5 - 2.0 THz region, with the angle-tuning of the KTP crystal in the OPO cavity. The maximum power of 1.4 mW at the peak was achieved at 1.4 THz.
