Journal ArticleDOI
Synthesized light transients.
Adrian Wirth,M. Th. Hassan,M. Th. Hassan,Ivanka Grguras,Justin Gagnon,A. Moulet,Tran Trung Luu,Stefan Pabst,Robin Santra,Zeyad A. Alahmed,Abdallah M. Azzeer,Vladislav S. Yakovlev,Vladislav S. Yakovlev,Volodymyr Pervak,Ferenc Krausz,Ferenc Krausz,Eleftherios Goulielmakis +16 more
TL;DR: Fine details of atomic-scale electron motion, such as the instantaneous rate of tunneling, the initial charge distribution of a valence-shell wavepacket, the attosecond dynamic shift of its energy levels, and its few-femtosecond coherent oscillations are revealed.
Journal ArticleDOI
Femtosecond all-optical synchronization of an X-ray free-electron laser
Sebastian A. Schulz,Ivanka Grguras,Ivanka Grguras,C. Behrens,Hubertus Bromberger,John Costello,Marie Kristin Czwalinna,M. Felber,Matthias C. Hoffmann,Markus Ilchen,Haiyun Liu,Tommaso Mazza,Michael Meyer,Sven Pfeiffer,Pawel Predki,S. Schefer,Carla Schmidt,U. Wegner,Holger Schlarb,Adrian L. Cavalieri,Adrian L. Cavalieri +20 more
TL;DR: The analysis indicates that the performance of this optical synchronization is limited primarily by the free-electron laser pulse duration, and should naturally scale to the sub-10 femtosecond level with shorter X-ray pulses.
Journal ArticleDOI
Ultrafast X-ray pulse characterization at free-electron lasers

Kabachnik,Th. Tschentscher,John Costello,Michael Meyer,Matthias C. Hoffmann,Matthias C. Hoffmann,Holger Schlarb,Adrian L. Cavalieri +19 more
TL;DR: In this article, single-cycle THz pulses from an optical laser were used to extend streaking techniques of attosecond metrology to measure the temporal profile and arrival time of individual FEL pulses with ∼5 fs precision.
Journal ArticleDOI
Invited article: attosecond photonics: synthesis and control of light transients.
M. Th. Hassan,Adrian Wirth,Ivanka Grguras,A. Moulet,Tran Trung Luu,Justin Gagnon,Volodymyr Pervak,Eleftherios Goulielmakis +7 more
TL;DR: The technological advances that have recently permitted the synthesis of light transients confinable to less than a single oscillation of its carrier wave and the precise attosecond tailoring of their fields are detailed.
Journal ArticleDOI

TL;DR: In this paper, the authors demonstrate a non-invasive scheme for temporal characterization of X-ray pulses with sub-femtosecond resolution using a spectroscopy streaking technique at LCLS (Linac Coherent Light Source).
