Abstract
The behaviour of an electron in a one-dimensional short-range potential subject to high-intensity short laser pulses was modelled numerically, by Su et al(1996 J. Phys. B: At. Mol. Opt. Phys.295755) who claimed that stabilization against ionization increases as the frequency is increased for a given intensity. Interpretation of these results as stabilization was challenged in a comment by Geltman (1999 J. Phys. B: At. Mol. Opt. Phys.32853). We argue that dynamical stabilization is more easily interpreted if comparisons between different frequencies are made for the same quiver amplitudes and pulse shapes.
