Narrowing of the emission angle in high-intensity Compton scattering

Abstract

We consider the emission spectrum of high-energy electrons in an intense laser field. At high intensities ($a_0\sim 200$) we find that the QED theory predicts a narrower angular spread of emissions than the classical theory. This is due to the classical theory overestimating the energy loss of the particles, resulting in them becoming more susceptible to reflection in the laser pulse.
