Abstract

We analyze free-electron-laser (FEL) oscillations in a perfectly synchronized optical cavity by solving the one-dimensional FEL equations. The radiation stored in the cavity can finally evolve into an intense few-cycle optical pulse in the high-gain and low-loss regime. The evolution of the leading slope of the optical pulse, which is defined from the front edge toward the primary peak, is found to play an important role in generating the intense few-cycle pulse. The phase space evolution of electrons on the second pass which interact with the leading slope of a SASE output pulse is obtained in a perturbation method similar to that used in our previous study for a SASE FEL. The resulting analytical solution of the leading slope in the second pass is shown to be approximated by that of a SASE FEL with FEL parameter greater than ρ. The same perturbation method can thus be used to the subsequent passes.
