High harmonic generation (HHG) has become a core pillar of attosecond science.
Traditionally described with field-based models, HHG can also be viewed in a parametric …

We demonstrate a hybrid dual-stage nonlinear compression scheme, which allows the
temporal compression of 330 fs-pulses down to 6.8 fs-pulses, with an overall transmission of …

We generate attosecond pulse train (APT) in argon driven by the high repetition rate (HR)
laser of the extreme light infrastructure-attosecond light pulse source (ELI-ALPS), providing …

Within the last two decades attosecond science has been established as a novel research
field providing insights into the ultrafast electron dynamics that follows a photoexcitation or …

We demonstrate experimentally that frequency resolved optical switching (FROSt) can be
used to characterize ultra-broadband pulses at high repetition rates up to 500 kHz …

The development of attosecond pump–probe experiments at high repetition rate requires the
development of novel attosecond sources maintaining a sufficient number of photons per …

High-order harmonics generated by a long intense femtosecond laser are known
experimentally to create attosecond pulse trains (APTs). In the time domain, an APT consists …

We report on the carrier-envelope phase (CEP) stabilization of a Yb-doped fiber amplifier
system delivering 30 μJ pulses at 100 kHz repetition rate. A single-shot, every-shot …

We study theoretically and experimentally high-order harmonic generation (HHG) using two
noncollinear driving fields focused in gases. We show that these two fields form a …

We present the design and implementation of a new, modular gas target suitable for high-
order harmonic generation using high average power lasers. To ensure thermal stability in …
