A longstanding dream…

Power outages, forest fires, electronic and infrastructure damages, personal injuries… Controlling lightning is a long time dream of mankind. Although lightning protection techniques have seen considerable progress in the past, the best external lightning protection to date is still based on the concept of the lightning rod, invented by Benjamin Franklin almost 300 years ago.

The LLR project aims to investigate and develop a new type of lightning protection using a laser-based technique to stimulate the number of upward lightning flashes with the aim of transferring cloud charges to the ground and thus to influence the incidence of downward natural lightning.

Free space publication laser telecommunication through fog

G. Schimmel, T. Produit, D. Mongin, J. Kasparian, and J.-P. Wolf, Optica 5, 1338 (2018) link Abstract: Atmospheric clearness is a key issue for free space optical communications (FSO). We present an active method to achieve FSO through clouds and fog, using ultrashort high-intensity laser filaments. The laser filaments opto-mechanically expel the droplets out of the …
