Abstract

We demonstrated a Čherenkov phase-matching method for monochromatic THz-wave generation using the difference frequency generation process with a lithium niobate crystal, which resulted in high conversion efficiency and wide tunability. We successfully generated monochromatic THz waves across the range 0.2–3.0 THz. We obtained efficient energy conversion in the low frequency region below 0.5 THz, and achieved a flat tuning spectrum by varying the pumping wavelength during THz-wave tuning.

THz-wave output mapping for various pumping wavelengths and corresponding THz-wave frequencies. The X-axis and Y-axis denote pumping wavelength λ1 and THz-wave frequency, respectively. The magnitude of the map values indicates the output voltage of the detector. Blue, green, and red curves are contour plots of 10 mV, 100 mV, and 1 V, respectively, of the detector output voltage.
