High-average-power femtosecond laser at 258 nm
Michael Müller, Arno Klenke, Thomas Gottschall +6
We present an ultrafast fiber laser system delivering 4.6 W average power at 258 nm based on two-stage fourth-harmonic generation in beta barium borate (BBO). The beam quality is c…
Energetic sub-2-cycle laser with 220 W average power
Steffen Hädrich, Marco Kienel, Michael Müller +12
Few-cycle lasers are essential for many research areas such as attosecond physics that promises to address fundamental questions in science and technology. Therefore, further advan…
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…
Ultra-short-pulse high-average-power Megahertz-repetition-rate coherent extreme-ultraviolet light source
R. Klas, A. Kirsche, M. Gebhardt +5
High harmonic generation (HHG) enables coherent extreme-ultraviolet (XUV) radiation with ultra-short pulse duration in a table-top setup. This has already enabled a plethora of app…
Wavelength-scale ptychographic coherent diffractive imaging using a high-order harmonic source
Getnet K. Tadesse, Wilhelm Eschen, Robert Klas +9
Ptychography enables coherent diffractive imaging (CDI) of extended samples by raster scanning across the illuminating XUV/X-ray beam thereby generalizing the unique advantages of…
