Generation of ~100-kW narrow-line far-infrared radiation from KTP off-axis THz parametric oscillator- 吳明雄 同學

國立清華大學光電工程研究所黃衍介教授指導的吳明雄、蔡瑋哲、邱鈺中三位同學，將兆赫波留置於高度吸收的非線性光學晶體中共振放大，產生高達十萬瓦且頻寬介於千分之一到萬分之一的超高亮度遠紅外光雷射。此桌上型雷射的輻射亮度直追，甚至超過世界上許多國家型的紅外光自由電子雷射，這項研究成果已刊登在今年6月號之光電領域期刊Optica。

Recently, the team of Institute of Photonics Technologies (IPT), National Tsing Hua University (NTHU) led by Prof. Yen-Chieh Huang successfully generated ultrahigh intensity far-infrared radiation through THz waves in KTP, and the related research result was published in the June 2019 issue of Optica journal. Compared with the bulky free electron lasers, the output intensity of the demonstrated table-top source is comparable or higher; thus, it opens up many possible new applications.
