At only one atom thick, graphene is an unusual material that defies ordinary methods of examination. Now a team of researchers at Iowa State University has found a path to uncovering unique new capabilities of graphene, by subjecting it to short laser pulses down to the range of 10 quadrillionths of a second.Graphene is already known to be an unusually efficient electrical conductor, considering its lack of heft. Headed by physicist Jigang Wang of the Department of Physics and Astronomy, the Iowa State research team discovered that graphene also has the ability to amplify light.
