Chromatic aberrations correction of attosecond high-order harmonic beams by flat-top spatial shaping of the fundamental beam
K. Veyrinas, M. Plach, J. Peschel +16
Attosecond pulses created by high-order harmonic generation in gases often exhibit strong chromatic aberrations, arising from the broad bandwidth and wavelength-dependent nonlinear…
Phase-matched high-order harmonic generation in pre-ionized noble gases
O. Finke, J. Vábek, M. Nevrkla +8
One of the main difficulties to efficiently generating high-order harmonics in long neutral-gas targets is to reach the phase-matching conditions. One issue is that the medium cann…
Optics-free focusing down to micrometer spot size and spectral filtering of XUV harmonics
K. Veyrinas, C. Valentin, D. Descamps +5
Controlling the wavefront of an extreme ultraviolet (XUV) high-order harmonic beam during the generation process offers to focus the beam without resorting to any XUV optics. By ch…
Mirrorless focusing of XUV high-order harmonics
L. Quintard, V. Strelkov, J. Vabek +8
By experimentally studying high-order harmonic beams generated in gases, we show how the spatial characteristics of these ultrashort XUV beams can be finely controlled under standa…
Role of Excited States In High-order Harmonic Generation
Samuel Beaulieu, Seth Camp, Dominique Descamps +8
We investigate the role of excited states in High-order Harmonic Generation by studying the spectral, spatial and temporal characteristics of the radiation produced near the ioniza…
Linear transport in stochastic media. Application to neutral transport in turbulent plasmas
Y. Marandet, A. Mekkaoui, D. Reiter +8
This work addresses linear transport in turbulent media, with emphasis on neutral particle (atoms, molecules) transport in magnetized fusion plasmas. A stochastic model for turbule…
