A Dual-Sideband Attosecond Interferometry Setup
Muhammad Jahanzeb, Marvin Schmoll, Paul Weizel +5
We present the development and implementation of an experimental setup designed to investigate attosecond photoionization delays using a dual-sideband RABBITT (Reconstruction of At…

Breakdown of the isotropic asymptotic approximation in two-colour photoionisation
Sooraj Rajendran, Miguel Benito de Lama, Praveen Kumar Maroju +24
The Wigner delay is defined as the energy derivative of the scattering phase of a particle in a given potential, unveiling the time taken (or gained) due to the interaction. The ch…

Impact of interference between two infrared pulses driving high harmonic generation
Sarang Dev Ganeshamandiram, Jahanzeb Muhammad, Marvin Schmoll +4
Extreme ultraviolet (XUV) interferometry is technically challenging to implement. One approach to generating interference between two XUV pulses relies on driving high-harmonic gen…
