【 摘 要 】

In this work the expression for the ponderomotive potential responsible for electron channeling in the field of crossed laser beams is analyzed. The influence of lasers crossing angle and electron velocity on the ponderomotive force is described in two plane waves approximation revealing «nonrelativistic inversion» phenomenon. Some estimations for the beam density of electrons channeled in such system are given.
