Abstract

In this paper an electromagnetically pumped free-electron- laser (FEL) with a tampered guide magnetic field is investigated by solving the Vlasov-Maxwell equations. The linear and nonlinear dispersion relations are derived. The nonlinear dispersion relation is solved to obtain the growth rate of the FEL. The energy conversion efficiency is estimated. The results show that the growth rate and the energy conversion efficiency for this kind of FEL may be obviously enhanced by adding a tapered guide magnetic field properly.
