Journal ArticleDOI
Nonlinear fast growth of water waves under wind forcing
TL;DR: In this article, a coordinate transformation is defined to map the forced nonlinear Schrodinger (NLS) equation into the standard NLS with constant coefficients, that has a number of known analytical soliton solutions.
Journal ArticleDOI
Amplification of intense light fields by nearly free electrons.

TL;DR: This work demonstrates that these unusual states of neutral atoms can be exploited to create a general ultrafast gain mechanism during laser filamentation, and shows that these states exist in rare gases, at and above atmospheric pressure, where they can act as a gain medium during Laser filamentation.
Journal ArticleDOI
White-light femtosecond Lidar at 100 TW power level
Massimo Petrarca,Stefano Henin,Nicolas Berti,Mary Matthews,Julio Chagas,Julio Chagas,Jérôme Kasparian,Jean-Pierre Wolf,Giovanni Marcellino Gatti,G. Di Pirro,Maria Pia Anania,Massimo Ferrario,A. Ghigo +12 more
TL;DR: In this paper, the white-light supercontinuum emission by a sub-petawatt laser system in the atmosphere via light detection and ranging measurements was characterized, and it was shown that as much as 1 J of super-continuum is generated in the air, corresponding to a conversion efficiency of 30 %.
Journal ArticleDOI
Non-linear photochemical pathways in laser-induced atmospheric aerosol formation
Denis Mongin,Jay G. Slowik,Elise Schubert,Jean-Gabriel Brisset,Nicolas Berti,Michel Moret,André S. H. Prévôt,Urs Baltensperger,Jérôme Kasparian,Jean-Pierre Wolf +9 more
TL;DR: Pre-existing water droplets strongly increase the oxidative properties of the laser-activated atmosphere, substantially enhancing the condensation of organics under laser illumination.
Journal ArticleDOI
Energy and wave-action flows underlying Rayleigh-Jeans thermalization of optical waves propagating in a multimode fiber (a)
K. Baudin,Adrien Fusaro,Josselin Garnier,Nicolas Berti,Katarzyna Krupa,Katarzyna Krupa,Iacopo Carusotto,Sergio Rica,Guy Millot,Guy Millot,Antonio Picozzi +10 more
TL;DR: In this article, it was shown that light condensation is driven by an energy flow toward the higher-order modes, and a bi-directional redistribution of the wave-action (or power) to the fundamental mode and to higher order modes.
