TL;DR: In this article, a review of the evolution of the self-focus phenomenon in light beams is presented, and the current status of this rapidly growing area of nonlinear optics and laser physics is discussed.

TL;DR: In this article, the fundamental physical mechanism responsible for self-focussing, filamentation, supercontinuum generation and conical emission of a powerful ultrashort laser pulse in a transparent optical medium is reviewed.

TL;DR: In this article, the authors observed a universal phenomenon of the competition among multiple filaments generated during the propagation of intense femtosecond laser pulses in air, and they showed that the fluorescence signal from the excitation of nitrogen molecules inside the plasma channel contains important information pertaining to the formation and interaction of multiple filament.

TL;DR: In this article, the authors present an overview of the recent progress in their laboratory concerning the remote sensing of chemical and biological agents/pollutants in air using filamentation-induced nonlinear fluorescence techniques.

TL;DR: In this article, a model of femtosecond laser pulse filamentation in the Kolmogorov atmospheric turbulence and employed the Monte Carlo method to model the propagation of several hundred laser pulses.
