摘要
Using a three-dimensional classical ensemble model,we investigate the dependence of relative frequency and relative initial phase for nonsequential double ionization(NSDI)of atoms driven by orthogonal two-color(OTC)fields.Our findings reveal that the NSDI probability is clearly dependent on the relative initial phase of OTC fields at different relative frequencies.The inversion analysis results indicate that adjusting the relative frequency of OTC fields helps control returning probability and flight time of the first electron.Furthermore,manipulating the relative frequency at the same relative initial phases can vary the revisit time of the recolliding electron,leading that the emission direction of Ar^(2+)ions is explicitly dependent on the relative frequency.
