The frequency characteristics of commercially available pyro-electric detectors have been compared in the range from 0.9 to 2.8 THz by using an intense continuously-tunable terahertz (THz)-wave source. We have found that the THz-wave interference inside the detector has considerable effect on the performance.
We have developed injection-seeded KTP optical parametric generator for DAST-DFG terahertz-wave source. Using a microchip Nd:YAG laser, the energy conversion efficiency of 10% and peak-power output of 2.5 MW were obtained at 1300 nm.
We have been developing novel widely tunable terahertz wave sources using nonlinear optical effects, and we have suggested a whole range of real-life applications using terahertz CT, metal mesh sensor, and time of flight tomography.
We have realized tunable terahertz wave parametric generator by using microchip Nd:YAG laser and observed output terahertz wave with tuning range of 0.9 - 3 THz, peak power of about 100 mW, and detected by schottky barrier diode.
We developed two new kinds of terahertz-wave parametric generators (TPG) by using compact pump sources. One TPG generates high energy and broadband THz-waves with high stability, the other has a potential to be a narrow-linewidth injection-seeded TPG.
