Material-specific high-resolution table-top extreme ultraviolet microscopy
Wilhelm Eschen, Lars Loetgering, Vittoria Schuster +9
Microscopy with extreme ultraviolet (EUV) radiation holds promise for high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-spe…
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…
Real-time phase-retrieval and wavefront sensing enabled by an artificial neural network
Jonathon White, Sici Wang, Wilhelm Eschen +1
In this manuscript we demonstrate a method to reconstruct the wavefront of focused beams from a measured diffraction pattern behind a diffracting mask in real-time. The phase probl…
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…
