Journal ArticleDOI
Ultrashort filaments of light in weakly ionized, optically transparent media
TL;DR: In this article, the authors present the landmarks of the 10-odd-year progress in this field, focusing on the theoretical modeling of the propagation equations, whose physical ingredients are discussed from numerical simulations.
Journal ArticleDOI
Wave collapse in physics: principles and applications to light and plasma waves
TL;DR: In this paper, the collapse of self-focusing waves described by the nonlinear Schrodinger (NLS) equation and the Zakharov equations in nonlinear optics and plasma turbulence is reviewed.
Journal ArticleDOI
Self-guided propagation of ultrashort IR laser pulses in fused silica.
Stellios Tzortzakis,L. Sudrie,Michel Franco,Bernard Prade,André Mysyrowicz,Arnaud Couairon,Luc Bergé +6 more
TL;DR: In this article, self-guiding is accompanied by pulse splitting and time compression, and a quasidynamic equilibrium between multiphoton ionization and self-focusing drives the filamentation process, while temporal dispersion plays a negligible role.
Journal ArticleDOI
Breakup and fusion of self-guided femtosecond light pulses in air.
TL;DR: Experiments show the breakup and the merging of filaments formed by the modulational instability of femtosecond optical pulses in air, which occurs in an optically Kerr regime and plays an important role in the guiding process.
Journal ArticleDOI
Ultrabroad Terahertz Spectrum Generation from an Air-Based Filament Plasma.

TL;DR: Experimental measurements of the frequency-angular spectrum generated by 130-fs laser pulses agree with numerical simulations based on a unidirectional pulse propagation model and show ring-shaped spatial distributions of the THz radiation are shown to be of universal nature.
