A self-consistent refractive index model for fast simulation of free-electron lasers
River R. Robles, Gabriel Marcus, Zhirong Huang
Modern x-ray free-electron lasers (XFELs) produce x-ray pulses of exceptional transverse coherence. This is due largely to the process of optical guiding by which the radiation is…

Self-Seeded FEL Wavelength Extension with High-Gain Harmonic Generation
Ling Zeng, Weilun Qin, Gang Zhao +5
We study a self-seeded high-gain harmonic generation (HGHG) free-electron laser (FEL) scheme to extend the wavelength of a soft X-ray FEL. This scheme uses a regular self-seeding m…
