Abstract
We have investigated the performance of classical models in the description of the single and double ionization of argon induced by 4-fs, 750-nm linearly polarized laser pulses by comparing the calculated quantities with existing experimental data, primarily the results of the systematic measurements of Kübel at al. [Phys. Rev. A 93, 053422 (2016)], in the intensity range (1–10). The comparison involved different one- and two-electron models based on the classical ensemble approximation. The analysis covered single- and double-ionization probabilities and their ratios, longitudinal momentum distributions of the and recoiled ions, and the carrier-envelope-phase-dependent asymmetry of the yield of the and ions.
