Intensity Dependence of Radiation Scattered by Electrons in a Laser Focus


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.
