Behavior of a Free-electron Laser Oscillator with a Hybrid Coaxial Wiggler

초록

We have analyzed the behaviors of a free-electron laser (FEL) with a hybrid coaxial wiggler and a normal wiggler for a free-electron laser oscillator. The radiation field is decomposed into fundamental and higher-order-Gauss Laguerre modes. A comparison of the behaviors of the radiation amplitudes of these modes and their efficiencies in the hybrid and the normal wigglers is made by using a 3D FEL code that we developed.
