Mutually phase-stable tunable attosecond soft X-ray attosecond pulses from a free-electron laser
River Robles, Kurtis Borne, Mathew Britton +16
We demonstrate the production of mutually phase-stable attosecond X-ray pulse pairs with tunable relative time delays and phases in a cascaded X-ray free-electron laser. We showcas…
The chemRIXS Instrument for the LCLS-II X-Ray Free Electron Laser
David J. Hoffman, Douglas Garratt, Matthew Bain +28
The chemRIXS instrument at the Linac Coherent Light Source offers new opportunities for studying solution-phase systems with time-resolved soft X-ray spectroscopy through the recen…
Nonlinear reversal of photo-excitation on the attosecond time scale improves ultrafast x-ray diffraction images
Anatoli Ulmer, Phay J. Ho, Bruno Langbehn +28
The advent of isolated and intense sub-femtosecond X-ray pulses enables tracking of quantummechanical motion of electrons in molecules and solids. The combination of X-ray spectros…
Imaging valence electron rearrangement in a chemical reaction using hard X-ray scattering
Ian Gabalski, Alice Green, Philipp Lenzen +24
We have observed the signatures of valence electron rearrangement in photoexcited ammonia using ultrafast hard X-ray scattering. Time-resolved X-ray scattering is a powerful tool f…
Attosecond Coherent Electron Motion in a Photoionized Aromatic Molecule
Taran Driver, Zhaoheng Guo, Erik Isele +50
In molecular systems, the ultrafast motion of electrons initiates the process of chemical change. Tracking this electronic motion across molecules requires coupling attosecond time…
"Beam `a la carte": laser heater shaping for attosecond pulses in a multiplexed x-ray free-electron laser
Siqi Li, Zhen Zhang, Shawn Alverson +19
Electron beam shaping allows the control of the temporal properties of x-ray free-electron laser pulses from femtosecond to attosecond timescales. Here we demonstrate the use of a…
Spectrotemporal shaping of attosecond x-ray pulses with a fresh-slice free-electron laser
River R. Robles, Kirk A. Larsen, David Cesar +14
We propose a scheme allowing coherent shaping, i.e., controlling both the amplitude and phase, of attosecond x-ray pulses at free-electron lasers. We show that by seeding an FEL wi…
Attosecond Delays in X-ray Molecular Ionization
Taran Driver, Miles Mountney, Jun Wang +34
The photoelectric effect is not truly instantaneous, but exhibits attosecond delays that can reveal complex molecular dynamics. Sub-femtosecond duration light pulses provide the re…
Attosecond X-ray Core-level Chronoscopy of Aromatic Molecules
Jia-Bao Ji, Zhaoheng Guo, Taran Driver +32
Attosecond photoemission or photoionization delays are a unique probe of the structure and the electronic dynamics of matter. However, spectral congestion and spatial delocalizatio…
Experimental Demonstration of Attosecond Pump-Probe Spectroscopy with an X-ray Free-Electron Laser
Zhaoheng Guo, Taran Driver, Sandra Beauvarlet +47
Pump-probe experiments with sub-femtosecond resolution are the key to understanding electronic dynamics in quantum systems. Here we demonstrate the generation and control of sub-fe…
Monitoring the evolution of relative product populations at early times during a photochemical reaction
Joao Pedro Figueira Nunes, Lea Maria Ibele, Shashank Pathak +31
Identifying multiple rival reaction products and transient species formed during ultrafast photochemical reactions and determining their time-evolving relative populations are key…
