Description
Recent results on ionization and fragmentation of atoms and (small) molecules with intense IR and XUV free-electron laser pulses will be presented. Emphasis is given to time-resolved and kinematically complete measurements using many-particle spectrometers (COLTRIMS or Reaction-Microscopes). In combination with modern short-pulse table-top lasers, or with high harmonic radiation sources based on IR up-conversion, or with large scale free-electron lasers like FLASH in Hamburg we try to unravel the correlated multi-particle dynamics in ultrafast processes occurring in atomic systems. For example, pump-probe experiments allow the observation of moving electronic wave-packets in bound sates of atoms, and in case of molecules vibrational and electronic excitations as well as the transfer of energy within a molecule can be imaged in real time.
