Title： Far Infrared free electron laser and its application

Reporter: Huang Yanjie (Institute of Photonics Technologies, National Tsinghua University, Hsinchu, Taiwan)

Time: 10:30 am-12:00 am, Friday, 19th, June.

Address: Lujiaxi Building(202)

Abstract: This talk included two parts, far-IR free-electron laser (FEL) and its applications. Prof. Huang Yanjie started his talk on the ultra-compact far-infrared (far-IR) free-electron laser (FEL) oscillator that he built at Stanford University during his graduation. This FEL oscillator employed an MeV thermionic gun as its injector. He later presented his recent study on THz superradiant FEL to achieve MW peak radiation power without a laser oscillator. Currently, we are actively helping the superconducting-accelerator team at Peking University to build a high peak and average-power THz FEL amplifier with tunablity between 15-85 cm-1. This far-IR FEL amplifier could become the most advanced source in the world. He also talked about the on-going effort on the realization of table-top far-infrared FEL driven by a laser modulated keV electron beam. As for applications, he gave a presentation as how a far-IR FEL could be useful to the study of chemistry, biology, medicine, and solid-state materials.
