| Abstract(in English) | For years, we have worked on the development of a high-power THz-wave source, based on parametric processes in a LiNbO3 crystal. Recently, the output THz-wave power of such parametric source was improved drastically. Moreover, high sensitive THz-wave detection and THz-wave amplification are possible by using same principle. However, the tuning range was limited. In this paper, we report the improvement of the is-TPG tuning range. Suppression of THz-wave absorption in the crystal by total reflection of a portion of the pump beam at the crystal surface increased the upper limit of the tunable range from 3.0 to 5.0 THz. |
