Abstract :
The modification induced on the well-known antisymmetric gain function of a free-electron laser when the gain coefficient g 0 ranges up to 10 is studied. Deviations from the linear regime for g0⩾0.5 are presented, and a simple perturbative analysis which accounts remarkably well for the corrections to the linear gain formula even for g0=10 is discussed. The effect of inhomogeneous broadening is also discussed
