We study the evolution of spectral intensity and degree of coherence of a new class of partially coherent beams, Hermite non-uniformly correlated array beams, in free space and in turbulence, based on the extended Huygens–Fresnel integral. Such beams possess controllable rectangular grid distributions due to multi-self-focusing propagation property. Furthermore, it is demonstrated that adjusting the initial beam parameters, mode order, shift parameters, array parameters and correlation width plays a role in resisting intensity and degree of coherence degradation effects of the turbulence.

Hermite非均匀相关阵列光束及其传播特性

我们基于扩展的惠更斯-菲涅耳积分研究了自由空间和湍流中一类新的部分相干光束、Hermite 非均匀相关阵列光束的光谱强度和相干程度的演变。由于多自聚焦传播特性，这种光束具有可控的矩形网格分布。此外，还证明了调整初始光束参数、模式阶数、位移参数、阵列参数和相关宽度在抵抗湍流的强度和相干度退化影响方面发挥作用。
