Intense laser pulse duration effects in the Coulomb explosion of the N{sub 2} molecule are studied using 10- and 40-fs laser pulses in the 10{sup 14}-10{sup 16} W cm{sup -2} intensity range. At 10 fs, no significant molecular stretching is observed during multi-ionization events up to the N{sup 2+}+N{sup 2+} fragmentation channel. Kinetic energy releases are larger and fragmentation yields are lower at 10 fs than at 40 fs due to the 1/R 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.
