The phase shift's influence of two strong-pulsed laser waves on effective interaction of electrons was studied. Considerable amplification of electron repulsion in the certain range of phase shifts and wave intensities is shown. That leads to electron scatter on greater distances than without an external field. The value of the distance can be greater on 2–3 order of magnitude. Considerable influence of the phase shift of pulses of waves on the possibility of effective attraction of electrons is also shown.
