Numerical Method for Free Electron Laser using an Overmoded Rectangular Waveguide
Weiwei Li, Heting Li, Zhigang He +3
Numerical simulation codes are basic tools for designing Free Electron Lasers (FELs). This paper describes a numerical method for the time-dependent, three-dimensional simulation o…
Generation of coherent two-color pulses at the two adjacent harmonics in a seeded free-electron laser
Zhouyu Zhao, Heting Li, Qika Jia
The growing requirements of pump-probe techniques and nonlinear optics experiments greatly promote the studies of two-color free-electron lasers (FELs). We propose a new method to…

In order to meet requirements of the synchrotron radiation users, a fully coherent VUV free electron laser (FEL) has been preliminarily designed. One important goal of this design…
Harmonics suppression effect of the quasi-periodic undulator in SASE free-electron-laser
Ai-Lin Wu, Qi-Ka Jia, He-Ting Li
In this paper, the harmonics suppression effect of QPUs in SASE FEL is investigated. The numerical results show that the harmonics power is reduced by using QPUs, but the fundament…
