为了有效地提高星地激光通信系统的通信性能，从推广的惠更斯-菲涅耳衍射原理出发，系统研究了矢量多高斯-谢尔模型光束在上行链路中的传输特性。研究结果表明，改变光束的横向相干长度能有效地改变其远场光强分布和大气湍流引起的光束展宽。另外，大气湍流会改变矢量多高斯光束的偏振度，但是在远场其偏振度会趋于一个固定值。该研究结果对星地激光通信等有着潜在的应用价值。

Based on the extended Huygens-Fresnel principle, the propagation properties of electromagnetic Gaussian multi-Schell model beams through atmospheric turbulence in a slanted path are investigated in detail. Results indicate that the changing of transverse coherence length has an effect on the far-field intensity distribution and the beam width induced by atmospheric turbulence of the laser beam. Besides, the degree of polarization of the electromagnetic Gaussian multi-Schell model beams can change with the propagation distance, and it can reach a certain value when the laser beam propagates through atmospheric turbulence in a slant path. This result indicates potential applications for satellite-to-ground or ground-to-satellite laser communications.
