This research present an analysis of the decomposition of Laguerre-Gaussian modes into Hermite-Gaussian modes when propagating through turbulence. This effect can be clearly observed by canceling the original Laguerre-Gaussian beam with another of different topological charge. The results of the propagations of these beams through Kolmogorov turbulence phase masks were analyzed, identifying which ones achieved the decomposition. The turbulences were then decomposed into the first 15 Zernike polynomials and used as new ‘Zernike turbulences’. We show that the turbulence internal process that allows the decomposition has a high correlation with a phase distortion based on a single Zernike polynomial or a combination of them.

本研究分析了在通过湍流传播时将拉盖尔-高斯模式分解为厄米特-高斯模式。通过用另一种不同的拓扑电荷抵消原始的拉盖尔-高斯光束，可以清楚地观察到这种效应。分析了这些光束通过 Kolmogorov 湍流相位掩模的传播结果，确定了哪些光束实现了分解。然后将湍流分解为前 15 个 Zernike 多项式并用作新的“Zernike 湍流”。我们表明，允许分解的湍流内部过程与基于单个 Zernike 多项式或它们的组合的相位失真具有高度相关性。
