Researchers build lasers for NASA climate studies

Montana State University electrical engineering professor Kevin Repasky (center) and graduate students Mike Obland (left) and David Hoffman stand next to a water-vapor detecting laser that may help scientists better understand the earth's climate. The group won a $1.1 million grant from NASA to advance their work on lasers for climate studies. The laser pictured fires through an opening in the roof of MSU's Cobleigh Hall.
