Taking slotted waveguide and helical wobbler as models, the influence of the initial velocity of the electrons and the induced magnetic field on the saturation characteristics of the amplifier was considered, and the self-consistent three-dimensional nonlinear equations of the wave injection interaction were derived. Based on this, The corresponding calculation software is compiled and the high frequency characteristics such as saturation efficiency and frequency bandwidth of cylindrical slotted waveguide free electron laser amplifier are studied by means of numerical analysis.
