Multiphoton ionization with three-dimensional light fields
Darius Köhnke, Hans-Christian Ahlswede, Tim Bayer +1
We report the first observation of free-electron angular momentum wave packets generated by atomic multiphoton ionization with bichromatic three-dimensional (3D) polarization-tailo…
Adiabatic dynamics in a V-type quantum system by oppositely chirped counterrotating circularly polarized laser pulses
D. Köhnke, T. Bayer, M. Wollenhaupt
Shaped free electron vortices (SEVs) have recently been studied using atomic (1+2) resonance-enhanced multiphoton ionization (REMPI) by oppositely chirped counterrotating circularl…
Measurement of ionization delays in atomic REMPI using photoelectron vortices
D. Köhnke, T. Bayer, M. Wollenhaupt
We study time-delays in atomic multiphoton ionization (MPI) using the phase-sensitive detection of photoelectron vortices. Photoelectron vortices are created by MPI with counter-ro…
Shaped free electron vortices
D. Köhnke, T. Bayer, M. Wollenhaupt
Since their first theoretical proposal [Ngoko Djiokap et al., Phys. Rev. Lett. 115, 113004 (2015)] and experimental demonstration [Pengel et al., Phys. Rev. Lett. 118, 053003 (2017…
Strong-field quantum control in the extreme ultraviolet using pulse shaping
Fabian Richter, Ulf Saalmann, Enrico Allaria +40
Tailored light-matter interactions in the strong coupling regime enable the manipulation and control of quantum systems with up to unit efficiency, with applications ranging from q…
Coherent Control of Photoelectron Wavepacket Angular Interferograms
Paul Hockett, Matthias Wollenhaupt, Thomas Baumert
Coherent control over photoelectron wavepackets, via the use of polarization-shaped laser pulses, can be understood as a time and polarization-multiplexed process. In this work, we…
