摘　　要：双光子共振增强了碱金属原子的非线性极化率，可以观测到多种非线性光学过程产生的非线性光谱．本文分析了有关的能级分布和光谱特点．The nonlinear spectroscopy created by many kind of optical processes are observed while two-photon resonance enhanced the atomic nonlinear susceptibility. The distribution of related energy levels and features of the spectroscopy are analysed.
