Gouy’s Phase Anomaly in Electron Waves Produced by Strong-Field Ionization Open
Ionization of atoms by strong laser fields produces photoelectron momentum distributions that exhibit modulations due to the interference of outgoing electron trajectories. For a faithful modeling, it is essential to include previously ove…

Momentum distributions from bichromatic ionization of atoms and molecules Open
When a sufficiently strong laser field acts on an atom or a molecule, ionization can occur. Electrons released in this process are accelerated by the laser field and the distribution of their final momenta can be measured. As opposed to us…

Double-slit photoelectron interference in strong-field ionization of the neon dimer Open
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept. The occurrence of interference rests on the lack of…

Direct Experimental Access to the Nonadiabatic Initial Momentum Offset upon Tunnel Ionization Open
We report on the nonadiabatic offset of the initial electron momentum distribution in the plane of polarization upon single ionization of argon by strong field tunneling and show how to experimentally control the degree of nonadiabaticity.…

Velocity map imaging of scattering dynamics in orthogonal two-color fields Open
In strong-field ionization processes, two-color laser fields are frequently used for controlling subcycle electron dynamics via the relative phase of the laser fields. Here we apply this technique to velocity map imaging spectroscopy using…
