TL;DR: The ability to trigger and guide high-voltage discharges with ionized filaments generated by femtosecond terawatt laser pulses with plasma filaments extended over the whole gap, providing a direct ohmic connection between the electrodes.

TL;DR: In this article, the authors demonstrate remote elemental analysis at distances up to 90m, using a laser-induced breakdown spectroscopy scheme based on filamentation induced by the nonlinear propagation of unfocused ultrashort laser pulses.

TL;DR: In this paper, the propagation of a multi-terawatt femtosecond laser pulse in air is studied as a function of initial chirp, and conditions for optimising air ionisation at long distance are presented.

TL;DR: In this paper, self-guided ionized filaments generated by ultrashort laser pulses are also able to induce water-cloud condensation in the free, sub-saturated atmosphere.

TL;DR: The filamentation of femtosecond light pulses in air is numerically and experimentally investigated for beam powers reaching several TW and evolution of the filament patterns can be qualitatively reproduced by an averaged-in-time (2D+1)-dimensional model derived from the propagation equations for ultrashort pulses.
