This book attempts to give a discussion of the physics and current and potential applications of the self-focusing of an intense femtosecond laser pulse in a tra-. We thus start with a very brief description of the fundamental physics of single filamentation of powerful femtosecond laser pulses in air. Intensity clamping is. We numerically investigated the femtosecond laser filamentation in a cell filled with argon of non-uniform density distribution. By comparison with the case of.

In nonlinear optics, filament propagation is propagation of a beam of light through a medium without diffraction. This is possible because the Kerr effect causes an index of refraction change in the medium, resulting in self-focusing of the beam. Filamentary damage tracks in glass caused by laser pulses were first Femtosecond laser filamentation in gaseous media[edit]. 1 Sep By ionizing air molecules without reaching the threshold for breakdown, femtosecond pulses form plasma channels that guide laser “filaments”. 2 Sep ADVANCES IN INTENSE FEMTOSECOND LASER FILAMENTATION IN AIR. 3. In the high intensity zone of the filament of a lin early polarized.

Space-based Femtosecond. Laser Filamentation. Final Report. Authors: V. Jukna1, A. Couairon1, I. Dicaire2, C. Praz2, C. Milian1, L. Summerer2. Affiliation: . We achieved femtosecond pulse filamentation of variable height and width by focusing the femtosecond laser beam in different layers inside the sample glass. We demonstrate experimental evidences that femtosecond filament-induced clean fingerprint fluorescence can indeed be employed to characterize the. 6 Aug Femtosecond laser filamentation in condensed media with Bessel beams. Krithika Dota, Abhishek Pathak, J. A. Dharmadhikari, D. Mathur, and. We experimentally demonstrate the generation of lasing action in the laminar ethanol/air flame on an alcohol burner array using femtosecond laser filament.
