Abstract

As an electron oscillates in an intense laser field, it acquires a highly nonlinear motion and emits X-ray radiation by nonlinear Thomson scattering. In this paper we present a numerical and experimental analysis of this radiation. We show that this radiative process becomes dominant at relativistic laser intensities ( Mathematical equation: $a_0>1$

), for which the laser light scatters off MeV electrons accelerated in the plasma.
