Show affiliationsWe present a fully quantum mechanical treatment of H+2 in intense laser pulses as short as 5 fs, focusing on the rotational dynamics of the dissociating fragments. The dependence of the dynamics on the pulse length and intensity is examined. We find that including nuclear rotation is essential for predicting the angular distribution of fragments even in these very short pulses. We further find that the axial recoil approximation holds for H+2 only when the laser pulse is longer than roughly 100 fs.
