Laser-subcycle control of electronic excitation across system boundaries

Abstract We report on the results of a joint experimental and numerical study sub-cycle laser field-driven electron dynamics that underlie population highly excited electronic states in multiply ionized argon dimers by recapture processes. Our experiments using few-cycle pulses with known carrier-envelope phase (CEP) combination reaction microscopy reveal distinct CEP-dependence emission process and, furthermore, small but significant CEP-offset to scenario which no are produced. With help classical ensemble trajectory simulations we trace down these different CEP-dependencies subtle differences laser-driven involve both cases transfer an from one ion across system boundary neighboring its transient capture this ion.
