Using a time-dependent approach the analysis and optimization of a planar FEL-amplifier with an axial magnetic field and an irregular waveguide is performed. By applying methods of nonlinear dynamics three-dimensional equations of motion and the excitation equation are partly integrated in an analytical way. As a result, a self-consistent reduced model of the FEL is built in special phase space. The reduced model is the generalization of the Colson-Bonifacio model and takes into account the…

A technique for efficiency enhancement in free-electron-laser and ''ubitron'' amplifiers is analyzed which makes use of both tapered wiggler and axial guide magnetic fields, and a modified pendulum equation is used to construct a small-signal theory of the efficiency enhancement.

It is shown that the motion of an individual test electron in a low-density relativistic electron beam propagating through a realizable planar wiggler magnetic field is nonintegrable and can become
Statistical theory of high-gain free-electron laser saturation.
This work proposes an approach, based on statistical mechanics, to predict the saturated state of a single-pass, high-gain free-electron laser, and shows that the initial relaxation of the laser can be described by the statistical mechanics of an associated Vlasov equation.
