摘要：

High-order harmonic generation with KrF and Ti:sapphire lasers is analyzed with an emphasis on contribution of multiply charged ions. It is confirmed that the intensity dependence of strong optical field ionization is explained by the Ammosov-Delone-Krainov (ADK) theory or by the barrier suppression ionization model regardless of the wavelength. The harmonic distributions are compared with the single-atom responses calculated using the short-range potential model with the effective interaction intensity determined by the ADK theory. From this analysis, we propose that for the KrF laser the harmonics above the 2 1 st in Ne and above the 13th in Ar may be due to doubly charged ions.
