in molecules induced by strong field ionization
Sascha Birkner, Federico Furch, Arnaud Rouzée, Claus
Strong field induced processes can give a detailed insight
into molecular electron and nuclear dynamics. We will investigate
here small and mid-size molecules with few cycle laser pulses
at intensities of 1014 W/cm2 to understand
excitation and ionization pathways, the induced multi-electron
dynamics and the formation of electronic wave-packets.
Excitation and acceleration
of atomic species in strong laser fields

Atoms exposed to strong laser fields do not necessarily ionize.
A substantial fraction of atoms is left in an excited state.
In particular we investigate the processes leading to a) excited
neutral atoms, b) neutral excited fragments after strong field
dissociation of molecules, c) high survival rates of Rydberg
atoms in strong fields. Moreover, the survival of atoms in
neutral excited states goes along with ultra strong kinematic
effects on neutral atoms in the focussed laser beam, which
are investigated using a direct imaging technique of excited
