317. Capturing the Fastest Dynamics in Materials using High Harmonic Sources

Dr Margaret Murnane (University of Colorado Boulder)

invited talks

In recent work, we captured intrinsic sub-femtosecond electron-electron scattering dynamics in materials for the first time. A powerful new technique called atto-ARPES (i.e. attosecond angle-resolved photoemission) enables deep-sub-fs measurements with sufficient energy resolution to separate different bands and states. This is the first way to directly probe the contribution of electron...

318. Attochirp Compensation and Characterization beyond C K-edge

Prof. Zenghu Chang (University of Central Florida)

invited talks

It is demonstrated by numerical simulations that attosecond chirp in the 300 to 1000 eV range can be partially compensated by the negative dispersion of ionized or unionized molecular hydrogen gas to achieve 25-as duration.

166. Generation and Characterization of Isolated Attosecond Pulses for Coincidence Spectroscopy at 100 kHz Repetition Rate

Dr Tobias Witting (Max-Born-Institut)

oral

Here we present an attosecond pump-probe beamline driven by a high power non-collinear optical parametric chirped pulse amplification (NOPCPA) system capable of running at a repetition rate of 100 kHz with a maximum output power of 24 W.

205. Isolated, Tunable Soft X-ray Attosecond Pulses at μJ Pulse Energy from a Free-electron Laser

Dr Taran Driver (Stanford PULSE Institute, SLAC National Accelerator Laboratory)

01/07/2019, 17:30

oral

We report the generation of isolated soft X-ray attosecond pulses with pulse energies of tens of microjoules using an X-ray free-electron laser.

81. Propagation-enhanced Generation of 100-eV Intense High-harmonic Continuum

Daniel Rivas (European XFEL)

01/07/2019, 17:45

oral

We present a robust generation of intense isolated attosecond pulses in the 100-eV spectral range for time-resolved nonlinear XUV spectroscopy. Through single-shot acquisitions and three-dimensional simulations we provide a complete description of the underlying processes.

178. Extreme-ultraviolet Refractive Optics

Oleg Kornilov (Max-Born-Institut)

01/07/2019, 18:00

oral

Here we demonstrate control over the refraction of XUV radiation by using a gas jet with a density gradient across the XUV beam profile. In a first set of experiments, a gas-phase prism and a gas-phase lens are demonstrated.
