Title

Intensity Dependence of Radiation Scattered by Electrons in a Laser Focus

Abstract

We computationally investigate how laser intensity affects the emission of nonlinear Thomson scattering. This computational model calculates the radiation emitted from free electrons when they accelerate violently in a high-intensity laser focus. As a result, these electrons emit harmonics of the driving laser frequency. We compare this model to measurements made in our lab where we use a pulsed-laser focused to an intensity of 10^18 W/cm^2 to create nonlinear Thomson scattering in this relativistic regime. These measurements are made with the added dimension of polarization. We measured the fundamental, second, and third harmonic emissions from electrons in a high-intensity laser focus.
