Electron dynamics in circularly-polarized laser and uniform electric fields: acceleration in vacuum

We solve exactly analytically the relativistic equation of motion of a single electron injected initially at an angle to the direction of propagation of a circularly-polarized plane-wave laser field, of arbitrary intensity, and a uniform electric field. It is shown, in principle, that the electron may be accelerated to high energies in this environment. (C) 2001 Elsevier Science B.V. All rights reserved.
