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…
XUV yield optimization of two-color high-order harmonic generation in gases
Ann-Kathrin Raab, Melvin Redon, Sylvianne Roscam Abbing +7
We perform an experimental two-color high-order harmonic generation study in argon with the fundamental of an ytterbium ultrashort pulse laser and its second harmonic. The intensit…
Highly versatile, two-color setup for high-order harmonic generation using spatial light modulators
Ann-Kathrin Raab, Marvin Schmoll, Emma R. Simpson +7
We present a novel, interferometric, two-color, high-order harmonic generation setup, based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each int…
Experimental observation of trajectories beyond the long in high order harmonic generation
S. Bengtsson, E. R. Simpson, N. Ibrakovic +4
We experimentally observe longer than long trajectory influence in high order harmonic generation (HHG) by varying the peak intensity of the driving laser field through either dire…
Spatial control of extreme ultraviolet light with opto-optical phase modulation
Anna Olofsson, Emma Rose Simpson, Neven Ibrakovic +2
Extreme-ultraviolet (XUV) light is notoriously difficult to control due to its strong interaction cross-section with media. We demonstrate a method to overcome this problem by usin…
Attosecond Pulse-shaping using a seeded free-electron laser
Praveen Kumar Maroju, Cesare Grazioli, Michele Di Fraia +41
Attosecond pulses are fundamental for the investigation of valence and core-electron dynamics on their natural timescale. At present the reproducible generation and characterisatio…
