Laser pulse-shape dependence of Compton scattering
Laser pulse-shape dependence of Compton scattering
Titov, A.; Kämpfer, B.; Shibata, T.; Hosaka, A.; Takabe, H.
Compton scattering of short and ultra short (sub-cycle) laser pulses off mildly relativistic electrons is considered within a QED framework. The temporal shape of the pulse is essential for the differential cross section as a function of the energy of the scattered photon at fixed observation angle. The partly integrated cross section is sensitive to the non-linear dynamics resulting in a large enhancement of the cross section for short and, in particular, for ultra-short flat-top pulse envelopes which can reach several orders of magnitude, as compared with the case of a long pulse. Such effects can be studied experimentally and must be taken into account in Monte-Carlo/transport simulations of %e+e− pair production in the interaction of electrons and photons in a strong laser field.
