Short-wavelength high-gain free-electron lasers (FELs) are now well established as a source of ultra-fast, ultra-brightness, longitudinally partial coherent light.

Simple analysis, numerical simulation and preliminary experimental results are presented. This approach can be robust and independent of frequency.
