Stabilization has also been observed in full time-dependent calculations for ultrashort high frequency pulses as a decrease in the ionization probability for increasing peak intensity; JPAPEH
11. see, e.g., J. H. Eberly and K. C. Kulander, Science 262, 1229 (1993). However, in many of these time-dependent calculations transfer of population to dressed excited states caused by the very fast pulse turn-on may be partly responsible for this decrease.SCIEAS

29. Interference stabilization, which occurs when the widths of adjacent Rydberg states overlap, does not play any role in the present case, since the ionization width of the (Formula presented) (Formula presented) state is two orders of magnitude smaller than its separation from the other (Formula presented) states. Transient stabilization can also be safely ruled out on the ground that the time-dependent wave function remains very close to the Floquet wave function during the entire pulse. A detailed comparison of these wave functions, for various pulse durations, will be reported elsewhere by the authors.
