Abstract
A theoretical model is presented which describes the time evolution of strong field photoionization as studied in recent XUV pump-IR probe attosecond tunneling (attosecond chronoscopy) experiments. The excitation of intermediate weakly bound states by an ultra-short XUV pulse (pump) is described within a sudden approximation. The photoionization of these states by a delayed strong IR pulse (probe) is described by solving the non-stationary Schrodinger equation. The results of the calculations show that the coherence of the excited states plays an important role resulting in quantum beats when the XUV pulse precedes the IR pulse. For a large overlap of the pulses a pronounced. ne structure in the cross-section is revealed. The calculations for Ne agree qualitatively with the experiment. Copyright (c) EPLA, 2008.
