dc.description.abstractWe studied the nuclear dynamics in diatomic molecules (N2 , O2 , and CO) following their interaction with intense near-IR few-cycle laser pulses. Using Coulomb-explosion imaging in combination with the pump-probe approach, we mapped dissociation pathways of those molecules and their molecular ions. We identi?ed all symmetric and asymmetric breakup channels for molecular ions up to N5+ 2 , O4+ 2 , and CO4+ . For each of those channels we measured the kinetic energy release (KER) spectra as a function of delay between the pump and probe pulses. For both N2 and O2 the asymmetric (3,1) channel is only observed for short (<20 fs) delays and completely disappears after that. We interpret this observation as a signature of electron localization taking place in dissociating molecular tri-cations when their internuclear separation reaches about 2.5 times the equilibrium bond length. This is a direct con?rmation that electron localization plays an essential role in the universal mechanism of enhanced ionization in homonuclear diatomic molecules. Using classical and quantum mechanical simulations of the time-dependent KER spectra, we identify the pathways and intermediate states involved in the laser-induced dissociation of those molecules.en_US
