▎ 摘　　要

For multi-photon processed with the linear dispersion in the high-intensity terahertz (THz) field, we have systematically investigated Hie temperature-dependent nonlinear optical response of graphene-based systems, including single layer grapheme, grapheme superlattice and gapped grapheme. In the intrinsic single layer graphene system, it demonstrates that, at low temperature, nonlinear optical conductivities of the third and fifth-order are respectively live and ten orders of magnitude larger than the universal conductivity with high-intensity and low frequency.THz wave.In the graphene, superlattice and gapped graphene systems, the optical responses enhanced because of the anisotropic massless and massive Dirac fermions.
