Query: Reconstruction of attosecond pulses in the presence of interfering
  dressing fields using the 100 kHz ELI-ALPS HR-1 laser system   Attosecond Pulse Trains (APT) generated by high-harmonic generation (HHG) of
high-intensity near-infrared (IR) laser pulses have proven valuable for
studying the electronic dynamics of atomic and molecular species. However, the
high intensities required for high-photon-energy, high-flux HHG usually limit
the class of adequate laser systems to repetition rates below 10~kHz. Here,
APT's generated from the 100 kHz, 160 W, 40 fs laser system (HR1) of the
Extreme Light Infrastructure Attosecond Light Pulse Source (ELI-ALPS) are
reconstructed using the Reconstruction of Attosecond Beating By Interference of
two-photon Transitions (RABBIT) technique. These experiments constitute the
first attosecond time-resolved photoelectron spectroscopy measurements
performed at 100 kHz repetition rate and the first attosecond experiments
performed at ELI-ALPS. These RABBIT measurements were taken with an additional
IR field temporally locked to the extreme-ultraviolet APT, resulting in an
atypical omega beating. We show that the phase of the 2-omega beating recorded
under these conditions is strictly identical to that observed in standard
RABBIT measurements within second-order perturbation theory. This work
highlights an experimental simplification for future experiments based on
attosecond interferometry (or RABBIT), which is particularly useful when lasers
with high average powers are used.
