Researchers use graphene to produce ultrashort infrared laser pulses

We already know that laser can be used to produce graphene (see here and here), and in 2010 researchers developed an ultra-fast mode-locked laser using Graphene. A recent research improved their graphene-based laser device to produce a broad spectrum of infrared wavelengths. This may be useful for applications such as fiber optic communications.

The researchers say that their results suggest it will be possible to create graphene-base lasers that emit light over the entire spectrum of visible light.
