Description
X-ray Free-Electron Laser Oscillators (XFELOs) driven by Diffraction Limited Storage Rings (DLSRs) promise ultra-narrow-bandwidth X-rays at high repetition rates. However, simulating the multi-pass laser build-up and saturation is a severe computational bottleneck. We present a simplified and highly efficient fast modeling framework for DLSR-XFELOs, which is capable of capturing power growth, temporal and spectral evolution of the radiation as well as beam quality change from pass to pass. We show the characteristic behavior of the longitudinal mode growth of such coupled system for long and short electron pulses.
