Nonsequential Double Ionization of Helium [PDF]
Physical Review Letters, 1997 Electron correlation effects in strong laser fields are investigated by using a simplified two electron model to calculate the double ionization rate in helium. In our model we make a correction to the single active electron approximation by including the effect of the outer electron on the inner one through a time-dependent potential.

Open Physics, 2023 Using the classical ensemble model, we investigate the effect of laser wavelength on the electron dynamics process of nonsequential double ionization (NSDI) for linear triatomic molecules driven by a counter-rotating two-color circularly polarized laser ...

Observation of nonsequential double ionization of helium with optical tunneling [PDF]
Physical Review Letters, 1992 We have measured the ion yields for helium ionized by 120 fs, 614 nm laser pulses for intensities near ${10}^{16}$ W/${\mathrm{cm}}^{2}$. We have found that for these ultrashort pulses the ${\mathrm{He}}^{+2}$ data exhibit a feature which saturates in parallel with the ${\mathrm{He}}^{+}$ signal indicating that the ionization may proceed ...

Nonsequential Double Ionization at the Single-Optical-Cycle Limit [PDF]
Physical Review Letters, 2004 We report differential measurements of Ar++ ion momentum distributions from nonsequential double ionization in phase-stabilized few-cycle laser pulses. The distributions depend strongly on the carrier-envelope (CE) phase. Via control over the CE phase one is able to direct the nonsequential double-ionization dynamics.

Optics Express, 2013 With the three-dimensional classical ensemble model, we investigate the correlated electron emission in nonsequential double ionization (NSDI) of argon atoms by few-cycle laser pulses. Our calculations well reproduce the experimentally observed cross-shaped structure in the correlated two-electron momentum spectrum [ Nature Commun. 3, 813 (2012)].

Nonsequential Double Ionization as a Completely Classical Photoelectric Effect [PDF]
Physical Review Letters, 2005 We introduce a unified and simplified theory of atomic double ionization. Our results show that at high laser intensities ($I \ge 10^{14}$ watts/cm$^2$) purely classical correlation is strong enough to account for all of the main features observed in experiments to date.

Results in Physics, 2023 The double ionization process of an Ar atom driven by a two-color counter-rotating circularly polarized (TCCP) laser pulse is theoretically investigated. Classical trajectory analysis reveals that a significant portion of Nonsequential Double Ionization (

Frustrated double ionization of argon atoms in strong laser fields [PDF]
EPJ Web of Conferences, 2019 We report coincidence measurements of frustrated double ionization of argon atoms with a reaction microscope. Experimental results show electron trap- ping process during double ionization has a clear transition from the nonsequential to the sequential ...
