“…Even though the classical model is robust, which has been demonstrated extensively in previous investigations [13][14][15][16], and also provides a straightforward interpretation with electron trajectory analysis [11,12], the physical picture of SDI is still unclear. Actually, to produce the experimental data, a scaling factor is adopted in [11,12] to shift the simulation curve.…”

The experimental observations of sequential double ionization (SDI) of Ar [A. N. Pfeiffer et al., Nature Phys. 7, 428 (2011)], such as the four-peak momentum distribution and the ionization time of the first and second electrons, are investigated and reproduced with a quantum model by including and excluding the e-e correlation effect. Based on the comparison of experiment and simulation, the role of e-e correlation in SDI is discussed. It is shown that the inclusion of e-e correlation is necessary to reproduce the momentum distribution of electrons.

“…Examples of such features are abundant. For example, ATI electrons [1], Freeman resonances [2], "fanlike" angular distributions of low-energy photoelectrons [3][4][5], "holography" in the photoelectron momentum distributions [6][7][8], and the conspicuous low-energy structures (LES) of photoelectrons by midinfrared pulses [9][10][11]. In addition, there are fine features observed only in very carefully detailed measurements.…”

We studied the elementary processes of excitation and ionization of atomic hydrogen in an intense 800-nm pulse with intensity in the 1.0 to 2.5 × 10 14 W/cm 2 range. By analyzing excitation as a continuation of above-threshold ionization (ATI) into the below-threshold negative energy region, we show that modulation of excitation probability and the well-known shift of low-energy ATI peaks vs laser intensity share the same origin. Modulation of excitation probability is a general strong field phenomenon and is shown to be a consequence of channel closing in multiphoton ionization processes. Furthermore, the excited states populated in general have large orbital angular momentum and they are stable against ionization by the intense 800-nm laser-they are the underlying reason for population trapping of atoms and molecules in intense laser fields.

“…The typical features of the photoelectron spectra of ATI are the plateaus in the highenergy part of the spectra [9] and the jet structures accompanied by the sub-peaks in the low-energy part of the spectra. [10] It is widely believed that the high-energy electron is related to the rescattering (recollision) mechanism, [11] while the low-energy part is believed to originate in direct photo-ionization. To date, little research [12][13][14][15] has been reported on the intensity dependence of the low-energy structure (LES), especially for a detailed comparison of the current state-of-the-art theory and the experimental data.…”

The above-threshold ionization of argon in an intense 70-fs, 400-nm linearly polarized laser pulse has been investigated by the velocity map imaging techniques, combined with an attosecond-resolution quantum wave packet dynamics method. There is a quantitative agreement in all dominant features between the experiment and the theory. Moreover, a peak-splitting phenomenon in the first energy peak has been observed at high pulse intensity. Further, through the theoretical analysis, an ac Stark splitting with evident resonant and nonresonant ionization pathways has been found to be the physical reason for the experimental observations.
