We describe first-principles in-plane calculations of non-sequential triple
ionization (NSTI) of atoms in a linearly polarized intense laser pulse. In a
fully classically correlated description, all three electrons respond
dynamically to the nuclear attraction, the pairwise e-e repulsions and the
laser force throughout the duration of a 780nm laser pulse. Nonsequential
ejection is shown to occur in a multi-electron, possibly multi-cycle and
multi-dimensional, rescattering sequence that is coordinated by a number of
sharp transverse recollimation impacts.Comment: 4 pages, 4 figure
