The effect of polarization controlling on coherent beam combining of two-fiber laser arrays of interferometric configuration is researched. Three kinds of arrays, built on the basis of Michelson and Mach-Zehnder interferometers, are investigated experimentally. It is found that polarization controlling is not necessary for coherent beam combining of the Michelson interferometric array but necessary for that of Mach-Zehnder interferometric arrays. These results reveal the important role of polarization in the self-organization process of interferometric laser arrays.
研究了偏振控制对干涉式配置的双光纤激光阵列相干光束合成的影响。实验研究了基于迈克尔逊干涉仪和马赫曾德尔干涉仪构建的三种阵列。发现偏振控制对于迈克尔逊干涉阵列的相干光束合成不是必需的，但对于马赫曾德尔干涉阵列的相干光束合成是必需的。这些结果揭示了偏振在干涉式激光阵列自组织过程中的重要作用。
