    Scientists are trying to control lightning with a giant laser


  • Article in Optics and Photonics News

    Can a “Super Laser” Tame Lightning? “The Germany-based laser and machine tool behemoth Trumpf announced that—working with scientists at the University of Geneva, Switzerland, and other organizations—it has hauled a 5-ton, 9-m-long “super laser” to the top of Säntis mountain in the Swiss Alps, and has installed and fired up the terawatt-scale light source. The ultimate goal of this audacious exercise: Demonstrate the ability of lasers to control and safely redirect lightning strikes…” Link to the article

    “Installé depuis le 18 mai au sommet du Säntis, dans les cantons d’Appenzell et St-Gall, un laser haute puissance vise à déclencher des éclairs et à guider la foudre loin des zones sensibles. Ce projet, intitulé «Laser Lightning Rod», est mené par un consortium européen dans lequel l’UNIGE a un rôle central. Des membres de la Section de physique de l’UNIGE ont participé au développement ainsi qu’au montage de la structure extérieure de l’expérience, dont certains éléments ont été installés…
