Engineering High-Order Harmonic Generation through Gas Confinement at Sub-Millimeter Lengths
Agata Azzolin, Gaia Giovannetti, Oliviero Cannelli +23
Attosecond light sources based on high-order harmonic generation (HHG) constitute to date the only table-top solution for producing coherent broadband radiation covering the spectr…
Synthesizing extreme-ultraviolet vector beams in a chip
Riccardo Piccoli, Marco Bardellini, Stavroula Vovla +11
Structured light has gained significant attention in recent years, especially in the generation and application of vector beams. These beams, characterized by a spatially varying p…
Spectrally tunable ultrashort monochromatized extreme ultraviolet pulses at 100 kHz
Tamás Csizmadia, Zoltán Filus, Tímea Grósz +15
We present the experimental realization of spectrally tunable, ultrashort, quasi-monochromatic extreme ultraviolet (XUV) pulses generated at 100 kHz repetition rate in a user-orien…
Efficient Coherent XUV Generation and Manipulation in Microfluidic Glass Devices
Anna Gabriella Ciriolo, Rebeca Martínez Vázquez, Gabriele Crippa +12
The development of compact and bright XUV and soft X-ray sources based on high-order harmonic generation is boosting advances towards understanding the behavior of matter with extr…
Controlling Floquet states on ultrashort time scales
Matteo Lucchini, Fabio Medeghini, Yingxuan Wu +10
The advent of ultrafast laser science offers the unique opportunity to combine Floquet engineering with extreme time resolution, further pushing the optical control of matter into…
Unravelling the intertwined atomic and bulk nature of localised excitons by attosecond spectroscopy
Matteo Lucchini, Shunsuke A. Sato, Giacinto D. Lucarelli +9
The electro-optical properties of most semiconductors and insulators of technological interest are dominated by the presence of electron-hole quasiparticles called excitons. The ma…
Space Charge Free Ultrafast Photoelectron Spectroscopy on Solids by a Narrowband Tunable Extreme Ultraviolet Light Source
Riccardo Cucini, Tommaso Pincelli, Giancarlo Panaccione +17
Here we report on a novel High Harmonic Generation (HHG) light source designed for space charge free ultrafast photoelectron spectroscopy (PES) on solids. The ultimate overall ener…
Polarization-control of absorption of virtual dressed-states in helium
Maurizio Reduzzi, Johan Hummert, Antoine Dubrouil +9
The extreme ultraviolet absorption spectrum of an atom is strongly modified in the presence of a synchronized intense infrared field. In this work we demonstrate control of the abs…
Vectorial optical field reconstruction by attosecond spectral interferometry
P. Carpeggiani, M. Reduzzi, A. Comby +12
An electrical pulse E(t) is completely defined by its time-dependent amplitude and polarisation direction. For optical pulses the manipulation and characterisation of the light pol…
Attosecond electronic recollision as field detector
P. Carpeggiani, M. Reduzzi, A. Comby +10
We demonstrate the complete reconstruction of the electric field of visible-infrared pulses with energy as low as a few tens of nanojoules. The technique allows for the reconstruct…
Tunable orbital angular momentum in high-harmonic generation
D. Gauthier, P. Rebernik Ribič, G. Adhikary +14
Optical vortices are currently one of the most intensively studied topics in optics. These light beams, which carry orbital angular momentum (OAM), have been successfully utilized…
