Researchers from the Iowa State University discovered that Graphene behaves like a laser when excited with very short femtosecond light pulses. Graphene has been shown to have two technologically important properties – population inversion of electrons and optical gain. This means that Graphene can be used to make a variety of optoelectronics devices, including broadband optical amplifiers, high-speed modulators, and absorbers for telecommunications and ultra fast lasers.

We already heard of some infra-red graphene related research: Infrared detection using graphene nanoribbons and a graphene-based technology for use in low-cost infrared imaging applications for the US military.
