Title: Electron acceleration by longitudinal electric field generated by colinearly overlapped two laser beams

Abstract

A localized beam like Gaussian beam in vacuum has an axial longitudinal electric field because of a finite radius caused by focusing. By the use of this longitudinal field, a new idea to efficiently accelerate electrons is presented. Two Gaussian beams having the fundamental mode TEM{sub 00} are directly applied to the electron acceleration, because an optimal longitudinal electric field can be created by overlapping the beams each other. In the overlapped region, when the phase difference between the two travelling waves is just a half wavelength, the optimal field has a significant peak of an axial field and its intensity pattern is similar to that of a TEM{sub 10} mode usually observed in the Gaussian beam. While, the transverse electric and magnetic fields cancel each other in this region. Hence, electrons that resonantly interact with the beams can be stably accelerated. {copyright} {ital 1996 American Institute of Physics.}
