Journal ArticleDOI
Plasma mirrors for ultrahigh-intensity optics
Cédric Thaury,Fabien Quéré,J. P. Geindre,Anna Lévy,T. Ceccotti,P. Monot,M. Bougeard,F. Réau,Pascal D'Oliveira,Patrick Audebert,Robin Marjoribanks,Ph. Martin +11 more
TL;DR: In this article, the temporal contrast of femtosecond (F2F) laser reflectors was investigated and it was shown that high-order harmonics of the laser frequency can be generated through two distinct mechanisms.
Journal ArticleDOI
Complete characterization of a plasma mirror for the production of high-contrast ultraintense laser pulses.
Gilles Doumy,Fabien Quéré,Olivier Gobert,M. Perdrix,Ph. Martin,Patrick Audebert,J. C. Gauthier,J. P. Geindre,T. Wittmann +8 more
TL;DR: A detailed experimental and theoretical study of the plasma mirror is presented that allows us to quantitatively assess the performances of this system and demonstrate that this system is very robust against changes in the pulse fluence and imperfections of the beam spatial profile, which is essential for applications.
Journal ArticleDOI
Coherent wake emission of high-order harmonics from overdense plasmas.
TL;DR: A new mechanism for high-order harmonic generation by reflection of a laser beam from an overdense plasma, efficient even at moderate laser intensities (down to Igamma2 approximately 4x10(15) W cm-2 microm2).
Journal ArticleDOI
Proton acceleration with high-intensity ultrahigh-contrast laser pulses.
T. Ceccotti,Anna Lévy,H. Popescu,F. Réau,Pascal D'Oliveira,P. Monot,J. P. Geindre,Erik Lefebvre,Ph. Martin +8 more
TL;DR: It is shown that the maximum proton energies are proportional to the p component of the laser electric field only and not to the ponderomotive force and that the characteristics of the proton beams originating from both target sides are almost identical.
Journal ArticleDOI
Direct Observation of Density-Gradient Effects in Harmonic Generation from Plasma Mirrors
Subhendu Kahaly,S. Monchocé,Henri Vincenti,Thomas Dzelzainis,Brendan Dromey,Matthew Zepf,Matthew Zepf,Ph. Martin,Fabien Quéré +8 more
TL;DR: This work demonstrates experimentally the key influence of the steepness of the plasma-vacuum interface on the interaction, by measuring the spectral and spatial properties of harmonics generated on a plasma mirror whose initial density gradient scale length L is continuously varied.
