(Phys.org) -- Ever since its discovery in 2004, graphene, the honey-comb arranged sheet of one atom thick carbon atoms, has continued to make waves in both the physics and engineering worlds. Now comes news from yet another research team heralding a new found property of the fascinating material. This time, as the group describe in their paper published in Physical Review Letters, its been found to have optical gain properties as a result of population inversion of electrons when struck with a short blast from a laser.
