Unleashing HHG Efficiency: The Role of Driving Pulse Duration
Robert Klas, Martin Gebhardt, Jan Rothhardt +1
High harmonic generation (HHG) is a crucial technology for compact, high-brightness extreme ultraviolet (XUV) and soft X-ray sources, which are key to advancing both fundamental an…
Laser-driven high-flux source of coherent quasi-monochromatic extreme ultraviolet radiation for coincidence spectroscopy
Julian Späthe, Sebastian Hell, Martin Wünsche +6
We present a source of coherent extreme ultraviolet (XUV) radiation with a flux of 10 photons per second at 26.5 eV. The source is based on high-harmonic generation (HHG) in…
Coincidence measurement of two-photon double ionization of argon through an autoionizing resonance
Sebastian Hell, Julian Späthe, Morten Førre +8
We present coincidence measurements of two-photon double-ionization (TPDI) of argon driven by femtosecond pulses tunable around 26.5 eV photon energy, which are obtained from a hig…
Quantitative EUV ptychography reveals nanoscale morphological responses of bacteria under physiological and antibiotic stress
Chang Liu, Leona Licht, Christina Wichmann +7
Table-top extreme ultraviolet (EUV) ptychography enables nanoscale, label-free, and quantitative imaging with intrinsic elemental sensitivity, offering a unique modality for subcel…
Table-top interferometry on extreme time and wavelength scales
S. Skruszewicz, A. Przystawik, D. Schwickert +12
High-resolution Fourier-transform spectroscopy using table-top sources in the extreme ultraviolet (XUV) spectral range is still in its infancy. In this contribution a significant a…
Bright, high-repetition-rate water window soft X-ray source enabled by nonlinear pulse self-compression in an antiresonant hollow-core fibre
M. Gebhardt, T. Heuermann, R. Klas +10
Bright, coherent soft X-ray (SXR) radiation is essential to a variety of applications in fundamental research and life sciences. So far, high photon flux in this spectral region ca…
High Speed and High Resolution Table-Top Nanoscale Imaging
G. K. Tadesse, R. Klas, S. Demmler +8
We present a table-top coherent diffraction imaging (CDI) experiment based on high-order harmonics generated at 18 nm by a high average power femtosecond fiber laser system. The hi…
