Abstract
Intense laser pulse duration effects in the Coulomb explosion of the molecule are studied using 10- and 40-fs laser pulses in the intensity range. At 10 fs, no significant molecular stretching is observed during multi-ionization events up to the fragmentation channel. Kinetic energy releases are larger and fragmentation yields are lower at 10 fs than at 40 fs due to the 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.
