文摘We report photoelectron energy spectra and angular distributions for ionization with elastic scattering in ultra- strong laser fields. Noble gas species with Hartree-Fock scattering potentials show a reduction in elastic rescat- tering with the increasing energy of ultrastrong fields and when the Lorentz deflection of the photoelectron exceeds its wave function spread. The relativistic extension of a three-step recollision model is well-suited to the ultrastrong intensity regime （〉10^17 W/cm2） that lies between traditional strong fields and extreme relativistic interactions.
