Advancements in light engineering have led to the creation of pulsed laser sources capable delivering high-repetition-rate, high-power few-cycle pulses across a wide spectral range, enabling exploration many fascinating nonlinear processes occurring all states matter. High-harmonic generation, one such process, which converts low-frequency photons driver field into soft x-rays, has revolutionized atomic, molecular, and optical physics, leading progress attosecond science ultrafast...
Abstract We generate attosecond pulse train (APT) in argon driven by the high repetition rate (HR) laser of extreme light infrastructure-attosecond source (ELI-ALPS), providing 100 kHz, 80 W, 1030 nm, 40 fs pulses from a fiber chirped-pulse amplification (fiber-CPA) system. Under current operating conditions harmonic generation beamline (HR-GHHG), we observed average duration to be 395 as measured using technique reconstruction beating interference two-photon transitions.

Photo-ionization induced ultrafast electron dynamics is considered as a precursor for the slower nuclear associated with molecular dissociation. Here, using ab initio multielectron wave-packet propagation method, we study overall many-electron dynamics, triggered by ionizing outer-valence orbitals of different tautomers prototype molecule more than one symmetry element. From time evolution initially created averaged hole density each system, identify distinctly charge responses in tautomers....
High-repetition-rate gas targets constitute an essential component in intense laser matter interaction studies. The technology becomes challenging as the repetition rate approaches kilohertz regime. In this regime, cantilever-based valves are employed, which can open and close tens of microseconds, resulting a unique kind characteristics both spatial temporal domain. Here we characterize piezo pulsed low density where it provides sufficient peak for high-harmonic generation while releasing...
Monitoring the carrier-envelope phase (CEP) is of paramount importance for experiments involving few cycle intense laser fields. Common measurement techniques include f-2f interferometry or stereo-ATI setups. These approaches are adequate, but challenging to implement on demand, at different locations as additional metrology tools, in laser-matter interaction experiments, such those prevalent sophisticated user beamlines. In addition there inherent difficulties CEP measured non-conventional...

Extreme ultraviolet (XUV) radiation is a tool of choice for studying ultrafast processes and atomic physics. Most experiments employing sources XUV radiation, such as high harmonic generation (HHG) or x-ray lasers, benefit from knowing the number photons delivered to target in every single shot, because possible shot-to-shot pulse fluctuation sources. Nonetheless, many setups lack noninvasive energy diagnostics, hindering simultaneous measurement utilization beam applications. We present an...

Along with the review of technological frame that will be available at Extreme Light Infrastructure Attosecond Pulse Source (ELI-ALPS) we present considerations applicable to large-scale attosecond sources driven by high-power laser pulses.
