The dynamics of a diatomic one-dimensional homonuclear molecule driven by a two-laser ﬁeld is investigated beyond the usual ﬁxed nuclei approximation. The dynamics of the nuclei is treated by means of Newton equations of motion; the full quantum description is used for the single active electron. The ﬁrst laser pulse (pump) excites vibrations of the nuclei, while the second very short pulse (probe) has the role of conﬁning the electron around one of the nuclei. We show how to use the radiation scattered in these conditions by the molecule to achieve real-time control of the molecular dynamics.
