Supercontinuum generation of ultrashort laser pulses in air at different central wavelengths
Stefan Skupin,Luc Bergé +1 more
TL;DR: In this paper, a unidirectional pulse propagation model and nonlinear evolution equations for femtosecond filaments in air is investigated for different laser wavelengths ranging from ultraviolet to infrared.
Self-guiding of femtosecond light pulses in condensed media: Plasma generation versus chromatic dispersion
Stefan Skupin,Luc Bergé +1 more
TL;DR: In this paper, the nonlinear self-guiding of ultrashort laser pulses in dielectric solids, such as fused silica, is investigated, and a basic set of propagation equations is derived analytically and a nonlinear Schrodinger model accounting for high-order dispersion, space-time focusing, self-steepening and plasma generation.
Role of the carrier-envelope phase in laser filamentation
TL;DR: In this article, the influence of the initial carrier-envelope phase (CEP) on the filamentation of ultrashort laser pulses in noble gas was numerically studied and the stability of the filament CEP against shot-to-shot fluctuations was examined.
Supercontinuum emission and enhanced self-guiding of infrared femtosecond filaments sustained by third-harmonic generation in air.
Luc Bergé,Stefan Skupin,G. Méjean,Jérôme Kasparian,Jin Yu,S. Frey,E. Salmon,Jean-Pierre Wolf +7 more
TL;DR: The long-range propagation of two-colored femtosecond filaments produced by an infrared (IR) ultrashort pulse exciting third harmonics (TH) in the atmosphere is investigated, both theoretically and experimentally, and it is shown that the coupling between the pump and TH components is responsible for a wide spectral broadening.
Pattern formation in the nonlinear Schrödinger equation with competing nonlocal nonlinearities.

- 27 Jun 2017
TL;DR: In this article, the authors study beam propagation in the framework of the nonlinear Schrodinger equation with competing Gaussian nonlocal nonlinearities and demonstrate that such system can give rise to self-organization of light into stable states of trains or hexagonal arrays of filaments, depending on the transverse dimensionality.
