| 摘 要： | 推导了高斯谢尔模光束通过ABCD光学系统的交叉谱密度矩阵，研究了该条件下光谱偏振度的变化情况。比较研究了高斯谢尔模光束通过自由空间和聚焦光学系统的情况。研究表明，在自由空间中传输足够远的距离后光谱偏振度将达到稳定，在聚焦光学系统中光谱偏振度在焦面位置附近有明显的起伏变化，两者都与光源参量的选择有关。特别指出，位于焦面上...

| Abstract: | The cross-spectral density matrix of Gaussian Schell-model beams through the ABCD optical system is derived,and the variation of the spectral degree of polarization under this condition is given.A compa-rison between the cases of Gaussian Schell-model beams through the free space and focal optical system is stu-died.The study shows that the spectral degree of polarization will tend to the stable value after a long-propagation distance in free space,and the spectral degree of polarization has a sharp fluctua... |
