Accurate model for the ultra-relativistic interactions between laser beams and electrons

Abstract

We present an accurate approach of the basic ultra-relativistic effects which occur at the interactions between laser beams and electrons and correspond to laser beam intensities greater than 1020 W/cm2. These effects are the generation of extremely bright pulses and the existence of a very large frequency spectrum of the radiation generated by this interaction, containing relative intense harmonics of orders higher than 800. Our results are in good agreement with the experimental results published in the literature.
