Research Summary

Our team develops state-of-the-art frequency-tunable THz-wave sources which exploit new THz-wave application fields. A nonlinear optical process is utilized for realizing the THz-wave source which lights up the THz-wave gray zone, and our original design and method will be demonstrated. We develop THz sources with high output, wide tunability, high stability and narrow linewidth.

Active collaboration with both internal and external research groups is carried out for exploring new applications by development of instrument combined with new THz-wave sources. Advanced THz-wave technologies are also being developed in cooperation with industry to establish practical THz-wave sources and technologies in the world.
