By using the rms beam width as the parameter to characterize the spreading property, the average spreading of Gaussian beam array propagates in non-Kolmogorov turbulence is studied. Numerical examples reveal that the beam width depends on the exponent value alpha, and the beam width in non-Kolmogorov turbulence is different from that in Kolmogorov turbulence with alpha=3.667. The beam width also depends on the distance between adjacent beamlets, the inner and outer scale parameters of the non-Kolmogorov turbulence. The beam array spreads more significantly with smaller inner scale and larger outer scale parameters.
以均方根束宽作为描述扩展特性的参数，研究了高斯光束阵列在非 Kolmogorov 湍流中的平均扩展。数值示例表明，束宽取决于指数值 alpha，并且非 Kolmogorov 湍流中的束宽与 alpha=3.667 的 Kolmogorov 湍流中的束宽不同。束宽还取决于相邻波束之间的距离、非 Kolmogorov 湍流的内尺度和外尺度参数。束阵列的内尺度越小，外尺度参数越大，扩展越明显。
