Electric conductivity induced by optomechanical laser filament effectThomas Produit, Elise Schubert, Denis Mongin, Guillaume Schimmel, Jérôme Kasparian and Jean-Pierre Wolf

We investigate the influence of ultrashort laser filaments on high-voltage discharges and spark-free unloading at various repetition rates and wind conditions. The effects on the conductivity of the optomechanical shockwave induced by the laser filament are also highlighted.
