Abstract :
Recently, the output power of injection-seeded THz-wave parametric generator (is-TPG) was improved drastically. It already reached few tens of kW@peak. 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.
