Abstract

The nonlinear evolution of a free-electron-laser (FEL) oscillator is investigated numerically for a configuration in which the FEL gain per pass in a high Q optical resonator is low. In this configuration, the number of passes required to reach the nonlinear saturation can be very large. In order to reduce the computer time, a formulation in which the discrete pass number is transformed to a continuous slow time variable is used. Preliminary results are presented for the case where the 2-D effects (diffraction, betatron oscillations) are neglected.
