WAVE-GUIDE FREE ELECTRON LASER - GAIN INHOMOGENEOUS BROADENING AND SATURATION

摘要

We discuss wave-guide Free Electron Laser gain formulae including inhomogeneous broadening and saturation effects. The analysis is not limited to the low gain regime, It is also proven that, after a proper redefinition, most of the ''empirical'' formulae exploited for the free space case can be utilised to model the wave-guide evolution.
