多孔径激光阵列相干合束是获得高功率、高亮度激光束的有效方法。为了设计更有效的多孔径激光阵列相干合成系统, 主要分析了三光束“品”字形、七光束六角形、十九光束大六角等工程应用中的典型激光阵列排布模式对合成功率的影响, 并基于MATLAB模拟了不同阵列排布情况下的激光相干合成情况, 讨论光束排列的位置误差、发射光束光轴角度偏移误差以及各个相干合成阵列激光器之间的活塞相位误差对合成效率的影响。结果表明, 不同的激光阵排布在观察位置处的光强分布差别很大；各光束之间的角度偏差越小, 初始相位差越小, 相干合成的效率越高。这些结果将对于指导设计多孔径激光阵列相干合成系统有重要意义。

Coherent beam combination of multi-aperture laser arrays is an effective way to obtain high power and high brightness beams. To design a more effective coherent combining system for multi-aperture laser arrays, the influence of typical arrangement of laser arrays is mainly analyzed in engineering applications, such as three-beam shaped, seven-beam hexagonal and nineteen-beam large hexagonal, on the combination efficiency, where MATLAB is employed to simulate the laser coherence under different array arrangements. The effect of the position error of the beam arrangement, the angle offset error of the beam axis, and the piston phase error between the coherent combining array lasers, on the combination efficiency is discussed. The results show that the intensity distributions of different laser arrays are very different. The smaller the angle deviation between the beams, the smaller the initial phase difference, and the higher the efficiency of coherent synthesis. These results are of great significant for the design of coherent synthesis system of multi aperture laser arrays.
