Abstract

Ionization of atoms by ultrashort one-cycle electromagnetic pulses is considered. First-order time-dependent perturbation theory for derivation of ionization probability by pulses with various field profiles is used. Numerical calculations for hydrogen and xenon atoms are done. Strong field-phase dependence of ionization probability is shown. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
