The propagation of intense femtosecond laser pulses in air and other transparent media is characterized by the emergence of self-guided structures, named filaments. Laser filamentation, and a fortiori multiple filamentation at high input powers, is characterized by the emergence of long-tailed statistical distributions of filament transverse and longitudinal position, spectral contents, intensity, or pattern within the laser beam. Based on analogue driving equations (Non-linear Schrödinger equation, NLSE), they can offer a model of oceanic rogue waves, i.e., sudden unpredictable waves of up to 25-30 m high over a smoother sea.We propose to investigate the statistical behaviour of filamentation so as to transfer the acquired knowledge to the description of oceanic rogue waves. Furthermore, we will characterize the multi-filamentation pattern in terms of phase transition in the same universality class as two-dimensional percolation, so as to offer a novel physical system for such class. These results will be used to as-sess the predictability and possibility risk assessment of rogue waves, based on the temporal revers-ibility of the NLSE.Based on the optimization of our filamentation model and its extension a fully three-dimensional model allowing arbitrary symmetries including multiple filamentation and their interaction, we propose to:-Definine the most suitable approach for including of the higher-order Kerr effect in filamentation codes, in light of the recent findings about their physical origin;-Investigating multiple filamentation to support upscaling of laboratory experiments to the atmospheric scale.-Determining the best laser conditions for optimizing specific filament properties in view of their main applications.These results will help defining the required specifications for high-power laser systems dedicated to atmospheric applications. In particular, it will provide information about the power and energy levels required to achieve effects on a macroscopic scale.
