Effects of angular spread in nonlinear Compton scattering
Original language description
We investigate the effects of the momentum spread of photon around incoming electrons during nonlinear Compton scattering of an elliptically polarized laser off an ultrarelativistic electron beam. It has been assumed to be a good approximation to neglect the angular spread in the strong-field QED codes considering its smallness in relativistic regime. Here, we scrutinize the validity of this approximation in the nonlinear Compton scattering. For our purpose, we improved the fully electron spin-and photon polarization-resolved Monte Carlo simulation method by employing the angle-resolved probability for high-energy photon emission in ultrastrong laser fields. The quantum operator method introduced by Baier and Katkov is employed for calculation of the probability within the quasiclassical approach and the local constant field approximation. Our simulation shows that the angular spread at emission has notable effects on angular distribution and polarization of outgoing particles. The width of angular distributions for electrons and emitted photons are increased. Meanwhile, the electrons polarization is reduced due to the correction of radiation reaction force, while the average polarization of photons is insensitive to the angular spread at emissions.
