Stimulated scattering by a relativistic electron beam in a uniform magnetic field - Nonlinear theory of double cyclotron resonance
Abstract
The nonlinear stage of double cyclotron resonance of electrons with the signal and pump fields is considered for FEL's which employ stimulated wave scattering and stimulated undulator radiation. The maximum achievable efficiency, both at and far from double resonance, is shown to be inversely proportional to N, the number of times the electrons oscillate in the signal and pump fields, and is relatively small. However, the optimum signal and pump field strengths at double resonance are just 1/sq rt mean N times the optimum strengths far from cyclotron resonance.
