Dose Constraints for High-Resolution Imaging of Biological Specimens with Extreme Ultraviolet and Soft X-ray radiation
Chang Liu, Leona Licht, Jan Rothhardt
We present a theoretical evaluation of radiation dose constraints for extreme ultraviolet (EUV) and soft X-ray microscopy. Our work particularly addresses the long-standing concern…
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…
Bayesian multi-exposure image fusion for robust high dynamic range ptychography
Shantanu Kodgirwar, Lars Loetgering, Chang Liu +6
The limited dynamic range of the detector can impede coherent diffractive imaging (CDI) schemes from achieving diffraction-limited resolution. To overcome this limitation, a straig…
High-speed and wide-field nanoscale table-top ptychographic EUV imaging and beam characterization with a sCMOS detector
Wilhelm Eschen, Chang Liu, Daniel S. Penagos Molina +3
We present high-speed and wide-field EUV ptychography at 13.5 nm wavelength using a table-top high-order harmonic source. By employing a scientific complementary metal oxide semico…
Visualizing the ultra-structure of microorganisms using table-top extreme ultraviolet imaging
Chang Liu, Wilhelm Eschen, Lars Loetgering +10
Table-top extreme ultraviolet (EUV) microscopy offers unique opportunities for label-free investigation of biological samples. Here, we demonstrate ptychographic EUV imaging of two…
Agile spectral tuning of high order harmonics by inteference of two driving pulses
Vittoria Schuster, Vinzenz Hilbert, Robert Klas +2
In this work the experimental realization of a tunable high photon flux extreme ultraviolet light source is presented. This is enabled by high harmonic generation of two temporally…
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…
Broadband holography-assisted coherent imaging -- towards attosecond imaging at the nanoscale
Wilhelm Eschen, Sici Wang, Chang Liu +7
In recent years nanoscale coherent imaging has emerged as an indispensable imaging modality allowing to surpass the resolution limit given by classical imaging optics. At the same…
Ultraviolet Dual Comb Spectroscopy: A Roadmap
Vittoria Schuster, Chang Liu, Robert Klas +4
Dual Comb Spectroscopy proved its versatile capabilities in molecular fingerprinting in different spectral regions, but not yet in the ultraviolet (UV). Unlocking this spectral win…
