“…The effect of the second counter-propagating wave is dumped due to the phase averaging. In the classical approach considered here, the acceleration of electrons is due to the ponderomotive force related to the linear and nonlinear parts of the Lorentz force as it is typical for the ponderomotive acceleration processes [10,15,16].…”

“…As long as we are interested in processes nonlinear to the field, the approach based on exact solution of equations of motion is the most appropriate. The exact solutions of classical equations of the electron motion in a single plane EM wave have been obtained by many authors using different methods (see [12][13][14][15][16] and references therein). A natural extension of this approach is to apply the same methods to the case of two interfering plane waves.…”

Abstract.The exact solution of the classical nonlinear equation of motion for a relativistic electron in the field of two electromagnetic (EM) waves is obtained. For the particular case of the linearly polarized standing EM wave in the planar optical cavity, the intensity of the nonlinear Compton scattering, the time of flight, and the momentum variation after the relativistic electron passes along the cavity axis are calculated in weak and strong field limits. The extent of these effects depends on the initial phase of the EM wave when the electron enters the cavity. This can be used for the production, diagnosis, and acceleration of relativistic electron (positron) microbunches.

“…In the classical approach considered here, the acceleration of electrons is due to the ponderomotive force related to the linear and nonlinear parts of the Lorentz force [10,16,17]. The facts that the electron-laser interaction is localized within the finite optical cavity and the accelerating force is nonlinear to the laser field circumvent the Lawson-Woodward (LW) theorem [21], which otherwise forbids the residual electron energy gain from EM waves in vacuum.…”

In this work one studies the effects arising from the inclusion of a stationary extraordinary mode in the resonant interaction of magnetized particles and perpendicularly propagating electrostatic waves. It is found that for a stationary mode frequency of the order of the Larmor frequency and with a suitably chosen amplitude, one is able to suppress the resonance which drives the weakly relativistic dynamics into chaos. Improved regular acceleration of initially low energy particles is thus attained. Analytical estimates of the optimal stationary mode amplitude is presented. A detailed study of the topological effects due to resonance suppression based on bifurcation analysis is performed. The main results are verified with the help of single particle numerical simulations.
