25th International Lightning Detection Conference & 7th International Lightning Meteorology Conference, March 12-15 – Ft. Lauderdale, Florida, USA
The ZEISS Research Award promotes outstanding achievements in the field of optics. Jean-Pierre Wolf, Professor at the University of Geneva, will be honored for his groundbreaking application of ultra-short, ultra-intense laser pulses in researching the earth’s atmosphere. His research makes it possible to find out more about pollutants in the earth’s atmosphere and potentially control lightning and condensation in clouds.
The awards will be presented during the ZEISS Symposium “Optics in the Quantum World” on 18 April 2018 at the ZEISS Forum in Oberkochen

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.

Prof. Jean-Pierre Wolf from the UNIGE team gave an interview on the German National Radio about laser rods. “These laser pulses are so intense that they change the characteristics of the air, they ionize the air and create an electrically charged channel, which has a diameter of only one tenth of a millimeter, but can be very long, up to 100 meters. A kind of ultra-intense Spaghetti.” Read the full interview
