摘　　要：该文通过一个二能级系统处于基态的原子被饱和光饱和激发,用一弱探测光对系统进行扫描,分析系统对探测光的吸收和色散与系统的线性极化率的关系,通过数值模拟分析吸收和色散曲线图掌握双光场作用下的介质的光学性质变化特性.In this paper,atoms in the ground state are excited by the saturating laser in a two-level system.When the weak probe laser scans the system,we research the relationships between the absorption and chromatic dispersion with the linear polarization rate of the system.By analyzing the absorption and dispersion curve through numerical simulation,the optical properties of the medium in the two-photon fields can be obtained.
