“…The fact that we were able to reproduce the quantum result with the classical analysis provides strong evidence that the renormalized Γ 1 (t) rate indeed accurately describes the dynamics of ionization, which is consistent with recent work on Coulomb-corrected SFA. [21] For the few-cycle pulse, the deconvolution that we performed for Figure 5 is problematic. Since our SFA model does not consider excited bound states, we can compare our SFA results with those obtained by numerically solving the TDSE only for probe pulses that do not excite atoms via single-photon transitions.…”

The formation and evolution of electron wave packets in the process of strong‐field ionization is one of the major research topics in attosecond science. The recently developed technique of nonlinear photoconductive sampling (NPS) requires a detailed understanding of these dynamics and provides a new approach to studying them. This work is motivated by the lack of a solid theoretical foundation for NPS measurements. The analysis shows that, for NPS in atomic gases, the strong‐field approximation provides an adequate description of the ionization dynamics but makes a significant error in predicting the spectral response function because the Coulomb interaction between photoelectrons and their parent ions significantly affects the motion of the electron wave packets.

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.
