Abstract

Intense laser pulse duration effects in the Coulomb explosion of the N2 molecule are studied using 10- and 40-fs laser pulses in the 10141016Wcm2 intensity range. At 10 fs, no significant molecular stretching is observed during multi-ionization events up to the N2++N2+ fragmentation channel. Kinetic energy releases are larger and fragmentation yields are lower at 10 fs than at 40 fs due to the 1R scaling of the molecular multi-ionization thresholds. These results open the way to Coulomb explosion imaging of neutral molecules using intense sub-10-fs laser pulses.
