Terahertz (THz) wave is one of the electromagnetic waves lies between radio waves and infrared waves, and shares the characteristics of both. It has many potential applications in wide area.

We are working on the development of high power and compact THz wave sources based on wavelength conversion technique in nonlinear crystal with lasers. Our unique THz wave sources allow us to detect reagents under high absorbed shielding materials, 3D THz computed tomography and many other imaging which were difficult with other systems in the past.
