摘要

我们进行时域光谱研究，并表明石墨烯片放大了入射太赫兹场。石墨烯发射光谱对激光泵浦强度的依赖表现出类似阈值的行为，证明了在太赫兹范围内存在负电导率和居数反转，为新型室温石墨烯基太赫兹激光器铺平了道路。

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.
