摘　　要：以正六边形排列的高斯光束为模型,计算了相干合成光强,分析了随机相位波动对合成光强的影响,并研究了合成光束的传输特性。结果表明,随机相位波动是影响合成光强及合成光束传输特性的主要因素,当随机相位波动均方差>2.0时,相干合成过渡到了非相干合成。Based on the model of Gaussian beams with hexagonal distribution, the coherent combining intensity is calculated, and the effect of the fluctuation of stochastic phases on coherent combined intensity is analyzed. The propagation property of the combined beam is also studied. A conclusion is drawn that the effect of the fluctuation of stochastic phases is the main factor influencing the intensity and the propagation of the combined beam and that the coherent combination becomes incoherent combination when the deviation of the fluctuation of stochastic phases is greater than 2. 0.
