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 …

The photoelectric effect is not truly instantaneous but exhibits attosecond delays that can
reveal complex molecular dynamics,,,,,–. Sub-femtosecond-duration light pulses provide the …

Electronic processes within atoms and molecules reside on the timescale of attoseconds.
Recent advances in the laser-based pump-probe interrogation techniques have made …

Photoionization of matter is one of the fastest electronic processes in nature. Experimental
measurements of photoionization dynamics have become possible through attosecond …

We study resonant two-photon ionization of helium atoms via the 1 s 3 p, 1 s 4 p and 1 s 5 p
1P1 states using the 15th harmonic of a titanium-sapphire laser for the excitation and a weak …

We present combined theoretical and experimental work investigating the angle-resolved
phases of the photoionization process driven by a two-color field consisting of an attosecond …

We report a joint experimental and theoretical study of a three-sideband (3-SB) modification
of the reconstruction of attosecond beating by interference of two-photon transitions …

Taking the two-photon ionization process in hydrogen atoms as an example, we propose a
scheme to decouple the partial-wave information in ultrafast ionization. By analyzing the …

Following up on a previous paper on two-color photoionization of Ar (3 p)[D. Bharti, Phys.
Rev. A 103, 022834 (2021) 2469-9926 10.1103/PhysRevA. 103.022834], we present …

The implementation of attosecond photoelectron–photoion coincidence spectroscopy for the
investigation of atomic and molecular dynamics calls for a high-repetition-rate driving source …
