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…
Table-Top Milliwatt-Class Extreme Ultraviolet High Harmonic Light Source
Robert Klas, Stefan Demmler, Maxim Tschernajew +5
Extreme ultraviolet (XUV) lasers are essential for the investigation of fundamental physics. Especially high repetition rate, high photon flux sources are of major interest for red…
High Speed and High Resolution Table-Top Nanoscale Imaging
G. K. Tadesse, R. Klas, S. Demmler +8
We present a table-top coherent diffraction imaging (CDI) experiment based on high-order harmonics generated at 18 nm by a high average power femtosecond fiber laser system. The hi…
Enhancing narrowband high order harmonic generation by Fano resonances
Jan Rothhardt, Steffen Hädrich, Stefan Demmler +4
Resonances in the photo-absorption spectrum of the generating medium can modify the spectrum of high order harmonics. In particular, window-type Fano resonances can reduce photo-ab…
