Ultra-high harmonic conversion of a seeded free-electron laser via harmonic optical klystron
Xiaofan Wang, Li Zeng, Weiqing Zhang +1
External seeded free-electron lasers (FELs) are compelling tools for generating fully coherent EUV and soft X-ray radiations. Echo-enabled harmonic generation (EEHG), the most typi…

Obliquely Incident Laser and Electron Beam Interaction in an Undulator
Xiaofan Wang, Chao Feng, Cheng-Ying Tsai +2
The angular drift of a laser beam is of particular concern in applications such as seeded free-electron lasers. A systematical study of the obliquely incident laser and electron be…
