The excitation scheme for photofragmentation of -type molecules (see picture) shows that, starting from the electronic ground state, a spectrally broad pulse (ω1) prepares outward-moving wave packets in two dissociative states. On reaching the fragment channel, a weak resonant laser pulse (ω2) with different carrier envelope phases (CEPs) prepares nuclear wave packets in different fragment channels. This leads to phase-dependent charge localization.
