A transmission channel may be characterized by its capacity, i.e., the largest quantity of mean mutual information transmitted between the emitter and the receiver. The channel we have studied is a light beam traveling in the low atmosphere, and the

We consider the problem of propagation of light in a bent step index circular core optical fibre. We first derive the exact equations in toroidal coordinates and give an analytic solution at first order with respect to the parameter λ/(curvature rad

International audience; We report filamentation of subpicosecond UV laser pulses with only millijoule energy in atmosphere. The results are in good agreement with a numerical simulation using a quasi-three-dimensional propagation code.

International audience; Two consecutive ultrashort laser pulses separated by 100 fs and polarized in orthogonal directions are shown to form a long femtosecond filament that connects both filaments created independently by each pulse from the interpl

We have observed that a pulse temporal self-compression takes place during the filamentation process. Pulse durations have been measured inside the filament by time-resolved self-diffraction between two identical filaments. We show this effect by com

Bulk damage induced by fs IR laser pulses in silica is investigated both experimentally and numerically. In a strong focusing geometry, a first damage zone is followed by a narrow track with submicron width, indicating a filamentary propagation. The

Femtosecond laser pulses propagating in air are investigated. For input powers as high as 25 times the self-focusing threshold, the pulses are shown to break up into two spots, which coalesce into a self-guided beam.
