Gamma-ray vortices from nonlinear inverse Thomson scattering of circularly polarized light

Abstract Inverse Thomson scattering is a well-known radiation process that produces high-energy photons both in nature and in the laboratory. Nonlinear inverse Thomson scattering occurring inside an intense light field is a process which generates higher harmonic photons. In this paper, we theoretic...
