Precollision effect on the double ionization of an Ar atom driven by a two-color counter-rotating circularly polarized laser pulse

Results in Physics, 2023
The double ionization process of an Ar atom driven by a two-color counter-rotating circularly polarized (TCCP) laser pulse is theoretically investigated. Classical trajectory analysis reveals that a significant portion of Nonsequential Double Ionization (
