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…
Spatial Control of Multiphoton Electron Excitations in InAs Nanowires by Varying Crystal Phase and Light Polarization
Erik Mårsell, Emil Boström, Anne Harth +14
We demonstrate the control of multiphoton electron excitations in InAs nanowires (NWs) by altering the crystal structure and the light polarization. Using few-cycle, near-infrared…
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…
Photoemission electron microscopy of localized surface plasmons in silver nanostructures at telecommunication wavelengths
Erik MÃ¥rsell, Esben W. Larsen, Cord L. Arnold +3
We image the field enhancement at Ag nanostructures using femtosecond laser pulses with a center wavelength of 1.55 micrometer. Imaging is based on non-linear photoemission observe…
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…
Controlled free-induction decay in the extreme ultraviolet
Samuel Bengtsson, Esben W. Larsen, David Kroon +8
Coherent sources of attosecond extreme ultraviolet (XUV) radiation present many challenges if their full potential is to be realized. While many applications benefit from the broad…
