Onset Of Saturation In A HighGain FreeElectron Laser
Abstract
We develop a perturbation series in powers of the radiation field strength in order to calculate nonlinear corrections to the highgain, exponentialamplification regime of a singlemode freeelectron laser, and thereby to study the onset of saturation in such a device. In such a series, contributions to the optical power gain come only from the oddorder terms. We give an estimate of the radiative power threshold at which nonlinear corrections become comparable to the usual smallsignal result.
