Abstract
Vibration, rotation, and dissociation of the simple diatomic molecular and ions perturbed by a strong laser pulse with linear polarization are considered in the framework of classic mechanics. The duration of the laser pulse influences the rotation of the molecular axis and the vibration of the internuclear separation. The molecular axis of the heavy molecular ion is strongly rotated at the end of an ultrashort laser pulse, whereas the alignment of the -ion axis occurs during the rise of a long laser pulse owing to quick dissociation. Angular distributions of protons in dissociation of the ion are calculated.
