Abstract :
An accurate analysis of the gain and the electron beam evolution in a free electron laser (FEL) amplifier in terms of the laser field intensity and of the initial momentum distribution of the electron beam is carried out using the exact solution of the beam evolution equation. The effect of the energy spread both in the small-signal and in the saturation regime is investigated.
