Redirection and Reshaping of Intense Extreme-Ultraviolet Radiation

Yu He, Alexander Magunia, Harijyoti Mandal +29

The goal to control short-wavelength radiation for the investigation and manipulation of ultrafast dynamics in quantum systems coevolves with the growing availability of extreme-ul…

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…

Two-color operation of a soft x-ray FEL with alternation of undulator tunes

E. A. Schneidmiller, I. J. Bermudez Macias, M. Beye +13

FLASH is the first soft X-ray FEL user facility, routinely providing brilliant photon beams for users since 2005. The second undulator branch of this facility, FLASH2, is gap-tunab…

Electronic Quantum Coherence in Glycine Molecules Probed with Ultrashort X-ray Pulses in Real Time

David Schwickert, Marco Ruberti, Přemys Kolorenč +25

Quantum coherence between electronic states of a photoionized molecule and the resulting process of ultrafast electron-hole migration have been put forward as a possible quantum me…

Imaging the He quantum halo state using a free electron laser

S. Zeller, M. Kunitski, J. Voigtsberger +24

We report on coulomb explosion imaging of the wavefunction of the quantum halo system He. Each atom of this system is ionized by tunnelionization in a femto second laser pulse…
