Impact of Coulomb interactions on ionization rates of noble gases in multi-cycle laser fields

In this study, we delve into the ionization dynamics of noble gases exposed to an 800 nm sine-squared laser pulse, placing emphasis on the influence of the Coulomb interaction on the ionization rate. Calculations are conducted under two conditions: one with and the other without considering the Coulomb potential. The results reveal the significant role of the Coulomb interaction in the dynamics of ionization. Our findings foster a deeper understanding of ionization processes within intense laser fields and aid in enhancing our existing theoretical frameworks.
