Ionization rate in an elliptically polarized laser field with respect to momentum at the tunneling exit point for noble atoms

Abstract

In this paper, we present a novel theoretical model analyzing tunneling ionization for noble atoms exposed to an elliptically polarized laser field. Employing a semiclassical ensemble approximation, the model assesses the impact of the dynamic Coulomb field and ionization potential. The integration of the Coulomb field effect notably aligns theoretical predictions with experimental data. The study underscores the pivotal role of ellipticity on the tunneling rate and affirms the model's applicability.
