为了研究高斯-谢尔模型(GSM)光束在电磁感应透明(EIT)材料中的传输特性，利用矩阵光学理论、衍射积分理论、相干偏振统一理论推导了GSM光束通过EIT材料的传输交叉谱密度方程的解析表达式。该表达式可以用于计算和研究GSM光束通过EIT原子气体的谱密度和相干度的变化。分析显示GSM光束的谱密度和相干度都可以通过控制光的拉比频率调控。此研究结果提供了一种新的调控光传输的方法和技术，同时该发现也为控制部分相干光的谱密度和相干度提供了一种新方法。

In order to study the propagation characteristics of Gaussian Schell-model (GSM) beams in electromagnetically induced transparency atomic vapor, the analytical expression was obtained for the cross-spectral density function of a Gaussian Schell-model beam passing through the electromagnetically induced transparency atomic vapor based on the matrix optics theory, diffraction integral theory and unified theory of coherence and polarization. The formula can be used in the study of the changes in the spectral density and spectral degree of coherence of the beam through the EIT atomic vapor. Numerical examples show that both the spectral density and the spectral degree of coherence of the GSM beam can be modulated by the Rabi frequency of the control light. The results have been provided a new method and technique for modulation the beam propagation. The findings indicate a new technique for controlling the spectral density and the spectral degree of coherence of the partially coherent light beam.
