Generation of 10-TW Attosecond X-Ray Pulses in a Free Electron Laser
E. A. Schneidmiller, S. Serkez, I. Zagorodnov +35
Attosecond pulses provide direct access to electron dynamics in atoms, molecules, and solids on their natural timescales. While table-top sources have achieved attosecond pulse dur…
A 2D Holographic Approach for All-Optical Single-Shot Temporal Characterization of SASE FEL Pulses
A. Azzolin, O. Cannelli, K. -F. Wong +31
X-ray Free-electron lasers (XFELs) deliver ultrashort and ultrabright radiation in a photon-energy range spanning from extreme ultraviolet to hard X-rays. Supporting pulse duration…
Probing atoms by periodically modulated electron bunches
A. B. Voitkiv, E. Schneidmiller, T. Pfeifer
When passing through an undulator in a Free Electron Laser, dense bunches of relativistic electrons split into micro-bunches, attaining a periodic space-time structure. We show tha…
First experiments with ultrashort, circularly polarized soft X-ray pulses at FLASH2
S. Marotzke, D. Gupta, R. -P. Wang +23
Time-resolved absorption spectroscopy as well as magnetic circular dichroism with circularly polarized soft X-rays (XAS and XMCD) are powerful tools to probe electronic and magneti…
Femtosecond charge and spin dynamics in CoPt alloys
Martin Pavelka, Simon Marotzke, Ru-Pan Wang +19
The use of advanced X-ray sources plays a key role in the study of dynamic processes in magnetically ordered materials. The progress in X-ray free electron lasers enables the direc…
Attosecond soft X-ray pulses generated by chirp-dispersed manipulation in an XFEL reveal nonlinear core-electron dynamics in neon
Lars Funke, Markus Ilchen, Svitozar Serkez +59
Free-electron lasers have demonstrated their capability of generating intense attosecond X-ray pulses, which are the key to studying electron dynamics at their natural time scale a…
