Abstract

The electron-electron correlation in nonsequential double ionization (NSDI) from aligned molecules by linearly polarized 800 nm laser pulses has been investigated with the three-dimensional classical ensemble model. The result shows that for the perpendicular alignment the two electrons involved in NSDI more likely exit the molecule into the opposite hemispheres as compared to the parallel alignment, which agrees well with the experimental result [Phys. Rev. Lett. 95, 203003 (2005)]. This alignment effect is qualitatively explained based on the suppressed potential barriers which are different for parallel molecules and perpendicular molecules. Additionally, the intensity dependence of the alignment effect is also explored.

Fig. 1
Fig. 1 The top row shows correlated electron momentum spectra in the direction parallel to the laser polarization for NSDI of nitrogen molecules at λ = 800 nm, I = 1.0 × 1014 W/cm 2. (a) molecules aligned parallel to the laser polarization, (b) molecules aligned perpendicular to the laser polarization. The second row displays the difference between the correlated electron spectra shown in the top row. Before taking their difference, the spectra have been normalized to the same number of events. (c) parallel minus perpendicular, (d) perpendicular minus parallel, and all negative values have been set to zero.
