我们认为电磁感应透明的概念只适用于低密度的原子，而对于高密度的原子，受激拉曼散射是完全主导的，入射的探测波不被透射，而是被转换成斯托克斯波。这种行为可以解释为探测波和斯托克斯波之间的线性吸收系数差异很大。我们已经验证了这一说法的实验中使用钠原子蒸气样品与缓冲气体和没有。使用刘维尔-麦克斯韦方程组和数值模拟的理论分析也支持我们的观察。
We claim that the concept of electromagnetically induced transparency is only valid for low atomic densities, and for high densities stimulated Raman scattering is totally dominant, where the incident probe wave is not transmitted but is converted to the Stokes wave. This behavior can be explained by the large difference in linear absorption coefficients between the probe and the Stokes waves. We have verified this claim by the experiments using sodium atomic vapor samples with and without a buffer gas. Theoretical analyses using the Liouville-Maxwell equations and numerical simulations also supported our observations.
