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…
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…
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…
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…
