In the past decades, both the increasing experimental evidence and some results of theoretical investigation on non-Kolmogorov turbulence have been reported. This has prompted the study of optical propagation in non-Kolmogorov atmospheric turbulence. In this paper, based on the thin phase screen model and a non-Kolmogorov power spectrum which owns a generalized power law instead of standard Kolmogorov power law value 11/3 and a generalized amplitude factor instead of constant value 0.033, the temporal power spectrum of irradiance fluctuations for a Gaussian-beam wave is derived in the weak fluctuation regime for a horizontal path. The analytic expressions are obtained and then used to analyze the influence of spectral power law variations on the temporal power spectrum of irradiance fluctuations.
在过去几十年里，已经报道了关于非柯尔莫哥洛夫湍流越来越多的实验证据和一些理论研究结果。这促使了对非柯尔莫哥洛夫大气湍流中光传播的研究。本文基于薄相位屏模型和一个非柯尔莫哥洛夫功率谱，该功率谱具有广义幂律而非标准柯尔莫哥洛夫幂律值11/3，以及一个广义幅度因子而非常数值0.033，在水平路径的弱起伏区域推导了高斯光束波辐照度起伏的时间功率谱。得到了解析表达式，然后用于分析谱幂律变化对辐照度起伏时间功率谱的影响。
