Scientists find that graphene can be used to build lasers

You already know that graphene can be used to make transistors , solar cells and even Sennheiser-quality cans . But if you think that’s about as cool as the carbon material can get, listen to this: It can also be used to make ultrashort-pulse lasers. According to scientists from a smattering of institutions, the atomic-scale chickenwire material has the ability to absorb light effectively — much like a sponge — over a broad range of wavelengths. It can then release the light it absorbs in quick bursts that last a few femtoseconds each (with one femtosecond lasting one millionth of one billionth of a second), which is what ultrashort-pulse lasers do
