We present a summary on the exact solutions to the classical relativistic equations of motion in the field of a plane electromagnetic wave and describe a modification of the averaging procedure, which yields equations governing the average electron motion in the field of a focused laser pulse when an electron oscillates at relativistic velocity. Applications to the barrier suppression ionization and Thompson radiation are briefly discussed.

AbstractAn effective theory of laser–plasma-based particle acceleration is presented. Here we treated the plasma as a continuous medium with an index of refraction nm in which a single electron propagates. Because of the simplicity of this model, we did not perform particle-in-cell (PIC) simulations in order to study the properties of the electron acceleration. We studied the properties of the electron motion due to the Lorentz force and the relativistic equations of motion were numerically solved and analyzed. We compared our results with PIC simulations and experimental data.

The Face

A uniform, unbounded, cold plasma stream, with relativistic velocity (0,U, 0), traverses a vacuum half-spacey> 0 and a dielectric half-spacey< 0. A plane electromagnetic wave in the plasma stream iny> 0 is incident obliquely on the face of the dielectric. The criterion for determining which characteristic waves are present in each half space is discussed, and it is shown that, for the polarization in which B is parallel toy= 0, there is one reflected wave and three transmitted waves. One of the latter can be an amplifying wave. A first approximation to the transmission and reflexion coefficients is found in the case when the density of the stream is low.
