“…1 together with the corresponding CEP-averaged TEMS. The yield ratio exhibits the characteristic knee shape [2,12] with an inflexion point around 3 × 10 14 W cm −2 and approaches the magnitude expected from pure SDI near 6 × 10 14 W cm −2 . The evolution of the curve with increasing intensity is accompanied by significant changes in the TEMS.…”

“…At high laser intensities, close to the saturation intensity for single ionization, double ionization is dominated by sequential double ionization (SDI), which can be described within the single-active-electron approximation. At lower intensity, nonsequential double ionization (NSDI) sets in, a regime where the double-ionization probability is orders of magnitude higher than predicted by SDI [2,12]. Different models incorporating electron correlation have thus been proposed to describe the dynamics leading to NSDI, as described in a recent review [13].…”

Complete characterization of single-cycle double ionization of argon from the nonsequential to the sequential ionization regime

Selected features of nonsequential double ionization have been qualitatively reproduced by a multitude of different (quantum and classical) approaches. In general, however, the typical uncertainty of laser pulse parameters and the restricted number of observables measured in individual experiments leave room for adjusting theoretical results to match the experimental data. While this has been hampering the assessment of different theoretical approaches leading to conflicting interpretations, comprehensive experimental data that would allow such an ultimate and quantitative assessment have been missing so far. To remedy this situation we have performed a kinematically complete measurement of single-cycle multiple ionization of argon over a one order of magnitude range of intensity. The momenta of electrons and ions resulting from the ionization of the target gas are measured in coincidence, while each ionization event is tagged with the carrier-envelope phase and intensity of the 4-fs laser pulse driving the process. The acquired highly differential experimental data provide a benchmark for a rigorous test of the many competing theoretical models used to describe nonsequential double ionization.

“…Concrete examples are the early measurements of a "knee" in the double ionization yield as a function of the laser-field intensity, which deviates from the predictions of sequential models in orders of magnitude [2], and the peaks in the electron momentum distributions in nonsequential double ionization (NSDI), as functions of the electron components p n (n = 1, 2) parallel to the laser-field polarization [3]. Such peaks occur at nonvanishing parallel momenta and cannot be explained by a sequential mechanism.…”

Laser-induced nonsequential double ionization at and above the recollision-excitation-tunneling threshold

We perform a detailed analysis of the recollision-excitation-tunneling (RESI) mechanism in laserinduced nonsequential double ionization (NSDI), in which the first electron, upon return, promotes a second electron to an excited state, from which it subsequently tunnels, based on the strong-field approximation. We show that the shapes of the electron momentum distributions carry information about the bound-state with which the first electron collides, the bound state to which the second electron is excited, and the type of electron-electron interaction. Furthermore, one may define a driving-field intensity threshold for the RESI physical mechanism. At the threshold, the kinetic energy of the first electron, upon return, is just sufficient to excite the second electron. We compute the distributions for helium and argon in the threshold and above-threshold intensity regime. In the latter case, we relate our findings to existing experiments. The electron-momentum distributions encountered are symmetric with respect to all quadrants of the plane spanned by the momentum components parallel to the laser-field polarization, instead of concentrating on only the second and fourth quadrants.

“…Such a sequential multiple ionization, long accepted as a reasonable approach to the formidable problem of a multielectron atom interacting nonperturbatively with an intense electromagnetic field, provides fair estimates of the various charge state appearance intensities [l] while the tunneling rates are in excellent agreement with single ionization yields [2]. However, more accurate measurements revealed systematic and very large deviations from the tunneling rates [2,3,4,5]: near appearance intensity under standard experimental conditions, the observed double ion yield is several orders of magnitude larger than predicted by the sequential rate. It soon became clear that electrons could not be considered as independent and that electron-electron correlation had to be taken into account.…”
