UNIGE team will organize the International Conference on Laser Filamentation, COFIL 2018, in Geneva on June 25- 29 2018. COFIL 2018 is the 7th of a very successful series of biennial conferences bringing together scientists working in the field of ultrashort and intense laser filamentation and its applications.

Abstract: We investigate the influence of ultrashort laser filaments on high-voltage discharges and spark-free unloading at various repetition rates and wind conditions. For electric fields well below, close to, and above the threshold for discharges, we observe remote spark-free unloading, discharge suppression, and discharge guiding, respectively. These effects rely on an indirect consequence of thermal deposition, namely, the fast dilution of ions by the shockwave triggered by the filament at each laser shot. This dilution drastically limits ion-ion recombination and increases the plasma channel conductivity that can still be non-negligible after tens or hundreds of milliseconds. As a result, the charge flow per pulse is higher at low repetition rates.
