Probing ultrafast electron dynamics in atoms and molecules
Abstract/Contents
- Abstract
- This dissertation explores two major lines of research concerning ultrafast electron dynamics in atoms and molecules. The first part investigates the dynamics of photoionization in intense laser fields on the attosecond time scale. A new technique using a weak probing field at half the frequency of the strong ionizing laser field reveals attosecond delays in the above-threshold ionization process. We observe the influence of the combined Coulomb-laser potential on the spectral phase of the photoelectron. In the second part, an experiment which imaged the uncoupling of electron motion from the molecular frame in rotating molecules is described. A coherent wave packet in the 4f Rydberg manifold of molecular nitrogen is created and its motion is probed in time. This allows for a direct observation in the time domain of a non-Born-Oppenheimer regime, known as the l-uncoupling regime, that up until now has only been inferred from spectroscopic data.
