Stimulated terahertz emission from optically pumped graphene
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.
