摘要
实验测量并比较了铯原子气室和吸收型中性衰减片对852.356 nm单色激光的吸收系数，以及两种介质吸收系数随入射光强变化的行为。对选择吸收和普遍吸收作了分析。采用单色光场与二能级原子系统相互作用的模型，就铯原子气室对852.356 nm共振光的吸收系数随入射光强的变化规律做了分析和拟合。
Abstract
We measured and compared the absorption coefficient of cesium (Cs) cell and neutral density filter (NDF) plate and the different behavior of the absorption coefficient with the variation of the 852.356 nm light intensity. We analyzed the general absorption and the selective absorption. We analyzed and fit the variation of the absorption coefficient of Cs cell with the variation of the 852.356 nm light intensity using the model of monochrome laser interacting with the two-level atomic system.
