Pump--probe x-ray microscopy of photo-induced magnetization dynamics at MHz repetition rates
Kathinka Gerlinger, Bastian Pfau, Martin Hennecke +11
We present time-resolved scanning x-ray microscopy measurements with picosecond photo-excitation via a tailored infrared pump laser at a scanning transmission x-ray microscope. Spe…
Tailoring Optical Excitation to Control Magnetic Skyrmion Nucleation
Lisa-Marie Kern, Bastian Pfau, Michael Schneider +12
In ferromagnetic multilayers, a single laser pulse with a fluence above an optical nucleation threshold can create magnetic skyrmions, which are randomly distributed over the area…
Deterministic Generation and Guided Motion of Magnetic Skyrmions by Focused He-Ion Irradiation
L. -M. Kern, B. Pfau, V. Deinhart +17
Magnetic skyrmions are quasiparticles with non-trivial topology, envisioned to play a key role in next-generation data technology while simultaneously attracting fundamental resear…
Attosecond multi-photon multi-electron dynamics
M. Kretschmar, A. Hadjipittas, B. Major +6
Multi-electron dynamics in atoms and molecules very often occur on sub- to few-femtosecond timescales. The available intensities of extreme-ultraviolet (XUV) attosecond pulses have…
Propagation-assisted generation of intense few-femtosecond high-harmonic pulses
B. Major, M. Kretschmar, O. Ghafur +11
The ongoing development of intense high-harmonic generation (HHG) sources has recently enabled highly nonlinear ionization of atoms by the absorption of at least 10 extreme-ultravi…
Highly nonlinear ionization of atoms induced by intense high-harmonic pulses
Björn Senfftleben, Martin Kretschmar, Andreas Hoffmann +7
Intense extreme-ultraviolet (XUV) pulses enable the investigation of XUV-induced nonlinear processes and are a prerequisite for the development of attosecond pump - attosecond prob…
First Observation of Self-Amplified Spontaneous Emission in a Free-Electron Laser at 109 nm Wavelength
J. Andruszkow
We present the first observation of Self-Amplified Spontaneous Emission (SASE) in a free-electron laser (FEL) in the Vacuum Ultraviolet regime at 109 nm wavelength (11 eV). The obs…
