Investigation of spatiotemporal output beam profile instabilities from differentially pumped capillaries
Martin Gebhardt, Emmanuel B. Amuah, Robert Klas +4
Differentially pumped capillaries, i.e., capillaries operated in a pressure gradient environment, are widely used for nonlinear pulse compression. In this work, we show that strong…
Temporal contrast enhancement of energeticlaser pulses by filtered self-phase-modulation broadened spectra
Joachim Buldt, Michael Mueller, Robert Klas +3
We present a novel approach for temporal contrast enhancement of energetic laserpulses by filtered SPM broadened spectra. A measured temporal contrast enhancement by at least 7 ord…
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…
