Abstract

We conduct time domain spectroscopy studies and shows that graphene sheet amplifies an incoming terahertz field. The graphene emission spectra dependency on laser pumping intensity shows a threshold like behavior, testifying the occurrence of the negative conductivity and the population inversion in the terahertz range, paving the way for a new class room temperature graphene based terahertz lasers.
