Photoelectron energy spectra from elastic rescattering in ultrastrong laser fields: A relativistic extension of the three-step model

Abstract: Using a relativistic adaptation of a three-step recollision model we calculate photoelectron energy spectra for ionization with elastic scattering in ultrastrong laser fields up to 24 a.u. (2 x 1019 W /cm 2). Hydrogenlike and noble gas species with Hartree-Fock scattering potentials show a reduction in elastic rescattering beyond 6 x 1016 W /cm 2 when the laser Lorentz deflection of the photoelectron exceeds its wave-function spread. A relativistic rescattering enhancement occurs at 2 x 1018 W /cm 2, commensur… Show more
