Three dimensional non-linear theory of the free electron laser
Abstract
This paper deals primarily with 3-D effects and efficiency enhancement methods in a steady state FEL amplifier configuration. We treat finite transverse dimension effects associated with (1) the wiggler field, (2) electron beam, and (3) radiation beam. Our formulation includes efficiency enhancement schemes such as spatially contouring the wiggler field as well as accelerating the electron beam. Finally, a 3-D example of a 10.6 microns FEL with enhanced efficiency is given.
