Abstract
We discuss how a prebunched beam may modify the dynamical behavior of a free-electron laser. We show that the lowest-order coefficients b(1, 2), modify the small signal dynamics, while the saturated regime is af fected by the higher-order coefficients. We also present an analysis o f the interplay between bunching, saturation and higher harmonic emiss ion during the FEL evolution.
