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-resolved attosecond near-threshold photoionization of molecular nitrogen
S. Haessler, B. Fabre, J. Higuet +10
We photoionize nitrogen molecules with a train of extreme ultraviolet attosecond pulses together with a weak infrared field. We measure the phase of the two-color two-photon ioniza…
High-order parametric generation of coherent XUV radiation
O. Hort, A. Dubrouil, M. A. Khokhlova +6
We observe a new regime of coherent XUV radiation generation in noble gases induced by femtosecond pulses at very high intensities. This XUV emission has both a reduced divergence…
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…
Inhomogeneous High-order Harmonic Generation in Krypton Clusters
H. Ruf, C. Handschin, R. Cireasa +9
High order harmonic generation from clusters is a controversial topic: conflicting theories exist, with different explanations for similar experimental observations. From an experi…
Role of the Ionic Potential in High Harmonic Generation
D. Shafir, B. Fabre, J. Higuet +9
Recollision processes provide direct insight into the structure and dynamics of electronic wave functions. However, the strength of the process sets its basic limitations - the int…
High-harmonic transient grating spectroscopy of NO2 electronic relaxation
H. Ruf, C. Handschin, A. Ferré +18
We study theoretically and experimentally the electronic relaxation of NO2 molecules excited by absorption of one ~400 nm pump photon. Semi-classical simulations based on trajector…
