Comparison of the returning electron wave packets from TDSE and SFA2 for Ne in a linearly polarized 800-nm laser field with parameters of (a) 5 fs and 1.8 × 1014 W/cm2, (b) 10 fs and 1.8 × 1014 W/cm2, and (c) 5 fs and 3.6 × 1014 W/cm2. Panel (d) shows the ratio of the single ionization yield from TDSE ( YTDSE+ ) over the single ionization yield of PPT ( YPPT+ ) for Ne in a linearly polarized 800-nm laser field as a function of intensity for pulse durations of 5 fs and 10 fs, respectively. In (a)–(c), the returning electron wave packets of SFA2 are renormalized according to the corresponding TDSE results. Adapted from Ref. [38].
