Propagation of Truncated Partially Coherent Cosh-Gaussian Beam in Non-Kolmogorov Turbulence

研究了截断部分相干双曲余弦高斯光束在非Kolmogorov湍流中的传输。基于广义惠更斯-菲涅耳原理,推导了截断部分相干双曲余弦高斯光束在非Kolmogorov湍流中传输的光强分布和桶中功率的解析表达式。通过数值模拟,研究了截断光束参数和非Kolmogorov湍流参数对传输性能的影响。研究结果可以为实际的工程应用如远程遥感和自由空间通信等提供一定的参考。

Propagation of partially coherent cosh-Gaussian beam in non-Kolmogorov turbulence is studied theoretically. Based on extended Huygens-Fresnel principle, the averaged intensity and the power in the bucket of partially coherent cosh-Gaussian beam in non-Kolmogorov turbulence are derived. The influence of beam parameters and turbulence parameters is studied numerically. The investigation presents a reference for engineering applications, for examole the remote sensing and the free-space communication.
