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…
Broadband hard X-ray attosecond pulses from extremely chirped electron beams
River Robles, Veronica Guo, David Cesar +10
Attosecond pulses from free-electron lasers have opened the doors to atomic site-specific studies of bound electronic dynamics on their natural, sub-femtosecond timescales. Key to…
Experimental demonstration of attosecond hard X-ray pulses
Ichiro Inoue, River Robles, Aliaksei Halavanau +24
We present the first direct experimental confirmation of attosecond pulse generation in the hard X-ray regime with a free-electron laser. Our experiment is based on measurements of…
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…
