The role of non-equilibrium populations in dark exciton formation
Paul Werner, Wiebke Bennecke, Jan Philipp Bange +15
In two-dimensional transition metal dichalcogenide structures, the optical excitation of a bright exciton may be followed by the formation of a plethora of lower energy dark states…
Formation of moiré interlayer excitons in space and time
David Schmitt, Jan Philipp Bange, Wiebke Bennecke +11
Moiré superlattices in atomically thin van-der-Waals heterostructures hold great promise for an extended control of electronic and valleytronic lifetimes, the confinement of excito…
Ultrafast element-resolved magneto-optics using a fiber-laser-driven extreme ultraviolet light source
Christina Möller, Henrike Probst, Johannes Otto +7
We present a novel setup to measure the transverse magneto-optical Kerr effect in the extreme ultraviolet spectral range at exceptionally high repetition rates based on a fiber las…
Direct Access to Auger recombination in Graphene
Marius Keunecke, David Schmitt, Marcel Reutzel +15
Auger scattering channels are of fundamental importance to describe and understand the non-equilibrium charge carrier dynamics in graphene. While impact excitation increases the nu…
Efficient orbital imaging based on ultrafast momentum microscopy and sparsity-driven phase retrieval
G. S. M. Jansen, M. Keunecke, M. Düvel +8
We present energy-resolved photoelectron momentum maps for orbital tomography that have been collected with a novel and efficient time-of-flight momentum microscopy setup. This set…
Diffractive shear interferometry for extreme ultraviolet high-resolution lensless imaging
G. S. M. Jansen, A. C. C. de Beurs, X. Liu +2
We demonstrate a novel imaging approach and associated reconstruction algorithm for far-field coherent diffractive imaging, based on the measurement of a pair of laterally sheared…
Spectrally resolved single-shot wavefront sensing of broadband high-harmonic sources
L. Freisem, G. S. M. Jansen, D. Rudolf +2
Wavefront sensors are an important tool to characterize coherent beams of extreme ultraviolet radiation. However, conventional Hartmann-type sensors do not allow for independent wa…
Spatially Resolved Fourier Transform Spectroscopy in the Extreme Ultraviolet
G. S. M. Jansen, D. Rudolf, L. Freisem +2
Coherent extreme ultraviolet (XUV) radiation produced by table-top high-harmonic generation (HHG) sources provides a wealth of possibilities in research areas ranging from attoseco…
Effect of soil temperature on one-way optical frequency transfer through dense-wavelength-division-multiplexing fibre links
T. J. Pinkert, O. Böll, G. S. M. Jansen +8
Results of optical frequency transfer over a carrier-grade dense-wavelength-division-multiplexing (DWDM) optical fibre network are presented. The relation between soil temperature…
