High-order harmonic generation in argon driven by short laser pulses: effects of post-pulse propagation and windowing
Aaron T. Bondy, Klaus Bartschat
We present ab initio calculations using the -matrix with time dependence (RMT) method for high-order harmonic generation (HHG) in argon in a short, intense pulse regime. The cal…
Extracting RABBITT-like phase information from time-dependent transient absorption spectra
J. Jakob, C. Bauer, M. -J. Ilhan +5
We explore how the spectral phase of atto\-second pulse trains influences the optical cross section in transient absorption (TA) spectroscopy. The interaction of extreme ultraviole…
Role of intermediate resonances in attosecond photoelectron interferometry in neon
M. Moioli, M. M. Popova, K. R. Hamilton +13
Attosecond photoelectron interferometry based on the combination of an attosecond pulse train and a synchronized infrared field is a fundamental technique for the temporal characte…
R-matrix with time-dependence calculations for three-sideband RABBITT in helium
A. T. Bondy, J. C. del Valle, S. Saha +4
Following up on a recent paper [Bharti et al., Phys. Rev. A 109 (2024) 023110], we compare the predictions from severalR-matrix with time-dependence calculations for a modified thr…
High-Order Harmonic Generation in Helium: A Comparison Study
A. T. Bondy, S. Saha, J. C. del Valle +4
We report a detailed study of high-order harmonic generation (HHG) in helium. When comparing predictions from a single-active-electron model with those from all-electron simulation…
Multi-sideband interference structures by high-order photon-induced continuum-continuum transitions in helium
D. Bharti, H. Srinivas, F. Shobeiry +7
Following up on a previous paper on two-color photoionization of Ar(3p) [Bharti et al., Phys. Rev. A 103 (2021) 022834], we present measurements and calculations for a modified thr…
Precise and accurate measurements of strong-field photoionisation and a transferrable laser intensity calibration standard
W. C. Wallace, O. Ghafur, C. Khurmi +12
Ionization of atoms and molecules in strong laser fields is a fundamental process in many fields of research, especially in the emerging field of attosecond science. So far, demons…
Experimental ionization of atomic hydrogen with few-cycle pulses
M. G. Pullen, W. C. Wallace, D. E. Laban +12
We present the first experimental data on strong-field ionization of atomic hydrogen by few-cycle laser pulses. We obtain quantitative agreement at the 10% level between the data a…
