摘要

本文详细探讨了不同相干态下动态Kolmogorov湍流对高斯-谢尔模型光束的影响。通过计算光束漂移、闪烁指数和Zernike多项式，在实验室水平上定量验证了这种湍流冲击光束的传播特性。实验证明，在不同的湍流强度下，与完全相干的光束相比，高斯-谢尔模型光束对湍流的影响更有弹性。这些结果在自由空间光通信中得到了应用。

Insensitivity of partially coherent Gaussian -Schell model beams to the impact of dynamic Kolmogorov type turbulence

ABSTRACT The effect of dynamic Kolmogorov kind of turbulence on Gaussian- Schell model beams in different coherence regimes have been explored in detail. The propagation characteristics of such turbulence impacted beams are quantitatively verified at the laboratory level by calculating beam wandering, scintillation index, and Zernike polynomials. It has been experimentally verified that Gaussian Schell model beams are more resilient to the impact of turbulence compared to their fully coherent counterparts under different turbulence strengths. These results find applications in free-space optical communications.

期刊介绍： The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope. Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. General topics covered include: • Optical and photonic materials (inc. metamaterials) • Plasmonics and nanophotonics • Quantum optics (inc. quantum information) • Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers) • Coherence, propagation, polarization and manipulation (classical optics) • Scattering and holography (diffractive optics) • Optical fibres and optical communications (inc. integrated optics, amplifiers) • Vision science and applications • Medical and biomedical optics • Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy) • Imaging and Image processing
