摘　　要：The physics of a system with broken symmetry is rich and interesting.Second harmonic generation(SHG)is one of the most useful methods for investigating surfaces,since it is only sensitive to the few layer surface atoms with broken spatial symmetry.Ultrafast surface SHG is especially useful for investigating nonlinear optics in nanophotonics.Although nano-optics is seenThe physics of a system with broken symmetry is rich and interesting. Second harmonic generation （SHG） is one of the most useful methods for investigating surfaces, since it is only sensitive to the few layer surface atoms with broken spatial symmetry. Ultrafast surface SHG is especially useful for investigating nonlinear optics in nanophotonics.
