摘要
本文对高斯－谢尔模光束通过光阑后的频谱传输与移动作了研究，分析了影响光束频谱移动的各种因素，数值计算结果表明，光阑的尺寸，光束的相干性和光束本身的谱线宽度对产生的频移量有很大影响。另一方面，谱线的移动量与传输距离有关，在不同传输距离上，移动各不相同。
In this paper. the propagation and change of the spectrum of light generated by Gaussian Schell-mode beam passing through an aperture is investigated. We find that the change of the spectrum depends on the size of the aperture, the effective correlation length and the spectrum width of the light source. On the other hand, the amount of the spectrum-shift depends on the propagation distance. i. e. in the near-field, the spectrum is red-shifted and in the far-field the spectrum is blue-shifted.
