In this paper we discuss the free-electron laser (FEL) dynamics, solving the Liouville equation ruling the longitudinal phase-space evolution of the electron beam. We evaluate the bunching coefficients and study the interplay between FEL dynamics and harmonic generation. The effect of the initial beam energy spread is also included.
