Electric Nondipole Effect in Strong-Field Ionization
A. Hartung, S. Brennecke, K. Lin +10
Strong-field ionization of atoms by circularly polarized femtosecond laser pulses produces a donut-shaped electron momentum distribution. Within the dipole approximation this distr…
Theory of Subcycle Linear Momentum Transfer in Strong-Field Tunneling Ionization
Hongcheng Ni, Simon Brennecke, Xiang Gao +8
Interaction of a strong laser pulse with matter transfers not only energy but also linear momentum of the photons. Recent experimental advances have made it possible to detect the…
Gouy's Phase Anomaly in Electron Waves Produced by Strong-Field Ionization
Simon Brennecke, Nicolas Eicke, Manfred Lein
Ionization of atoms by linearly polarized strong laser fields produces cylindrically symmetric photoelectron momentum distributions that exhibit modulations due to the interference…
Kinematically complete experimental study of Compton scattering at helium atoms near the ionization threshold
Max Kircher, Florian Trinter, Sven Grundmann +15
Compton scattering is one of the fundamental interaction processes of light with matter. Already upon its discovery [1] it was described as a billiard-type collision of a photon ki…
Strong-field photoelectron holography beyond the electric dipole approximation: a semiclassical analysis
Simon Brennecke, Manfred Lein
Strong-field photoelectron holography denotes the interference of various electron paths in laser-induced ionization of atoms, leading to interference patterns in the final momentu…
Magnetic fields alter tunneling in strong-field ionization
A. Hartung, S. Eckart, S. Brennecke +16
When a strong laser pulse induces the ionization of an atom, momentum conservation dictates that the absorbed photons transfer their momentum to the electron and its pa…
