Abstract

We consider the motion of an electron under the influence of two counterpropagating multimode electromagnetic waves and a longitudinal electrostatic field. General equations of motion are presented from which a simple wavelength scaling condition is deduced for minimizing detrapping effects. An interaction coherence time or a maximum useful interaction length parameter is derived. The full equations of motion are numerically solved for a variety of external and initial conditions.
