Advancements in light engineering have led to the creation of pulsed laser sources capable
of delivering high-repetition-rate, high-power few-cycle laser pulses across a wide spectral …

Ultrafast electron dynamics drive phenomena such as photochemical reactions, catalysis,
and light harvesting. To capture such dynamics in real-time, femtosecond to attosecond light …

We present the experimental realization of spectrally tunable, ultrashort, quasi-
monochromatic extreme ultraviolet (XUV) pulses generated at 100 kHz repetition rate in a …

In this work, a continuously tunable extreme ultraviolet source delivering a state-of-the-art
photon flux of> 10^ 11 ph/s/eV spanning from 50 eV to 70 eV is presented. The setup …

Tunable attosecond pulses are necessary for various attosecond resolved spectroscopic
applications, which can potentially be obtained through the tuning of high harmonic …

We theoretically demonstrate the possibility to tune the temporal waveform of unipolar
pulses of femtosecond duration emitted from a multilevel resonant medium. This is achieved …

High-energy-synthesized laser pulses through a nonlinear frequency-conversion process
with different characteristics, such as polarization, central wavelength, and pulse duration …

We demonstrate loss-free generation of 3 mJ, 1 kHz, few-cycle (5 fs at 750 nm central
wavelength) double pulses with a pulse peak separation from 10 to 100 fs, using a helium …

Wave packet interferometry with vacuum ultraviolet light has been used to probe a complex
region of the electronic spectrum of molecular nitrogen, N 2. Wave packets of Rydberg and …

Phase‐matching of high harmonics with abruptly auto‐focusing ring‐Pearcey–Gaussian
beams is investigated. The slowly diffracted propagation after the auto‐focusing of the …
