Comparison Between, and Validation Against an Experiment of, a Slowly-Varying Envelope Approximation Code and a Particle-in-Cell Simulation Code for Free-Electron Lasers

L. T. Campbell, H. P. Freund, J. Henderson +3

Free-electron lasers (FELs) operate at wavelengths down to hard x-rays, and are either seeded or start from noise. There is increasing interest in x-ray FELs that rely on Self-Ampl…
