Two-Stage Laser Could Make Rain, Lightning
UNION PARK, Fla. and TUCSON, Ariz., April 18, 2014 — Weather is beyond human control — or is it? A team from the University of Central Florida (UCF) College of Optics & Photonics and the University of Arizona are developing a technique to trigger rain and lightning in clouds with a high-energy laser beam. The researchers have discovered that surrounding a laser beam with a second beam creates an energy reservoir that can sustain the central beam over long distances. This second “dress” beam helps prevent the...
