Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Attosecond transient absorption is one of the promising new techniques being developed to
exploit the availability of sub-femtosecond extreme ultraviolet (XUV) pulses to study the …

Ultrafast extreme ultraviolet (XUV) transient absorption spectroscopy measures the time-and
frequency-dependent light losses after light–matter interactions. In the linear region, the …

Laser-driven recollision physics is typically accessible only at field intensities high enough
for tunnel ionization. Using an extreme ultraviolet pulse for ionization and a near-infrared …

Progress in high-harmonic generation has led to high-energy attosecond pulses with cutoff
above the carbon 1 s edge (283.8 eV). These pulses are essential to extend time-resolved …

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 …

Nonlinear spectroscopies are utilized extensively for selective measurements of chemical
dynamics in the optical, infrared, and radio-frequency regimes. The development of these …

Layered two-dimensional halide perovskites (2DHPs) exhibit exciting non-equilibrium
properties that allow the manipulation of energy levels through coherent light–matter …

We present a time-and phase-resolved, background-free scheme to study the extreme
ultraviolet dipole emission of a bound electronic wave packet, without the use of any …

The advent of ultrafast laser science offers the unique opportunity to combine Floquet
engineering with extreme time resolution, further pushing the optical control of matter into …
