摘要:

提出了一种利用微透镜阵列实现相干合成的新方法。这些标准组件用于相干光束分裂和5 x 5光束组合的原理验证实验。在这里,实现了90%以上的组合效率。我们称这种新概念为混合孔径。

英文摘要:

A novel concept for coherent beam combining is presented based on a simple setup with microlens arrays. These standard components are used in a proof-of-principle experiment for both coherent beam splitting and combination of 5 x 5 beams. Here a combination efficiency above 90% is achieved. We call this novel concept mixed aperture.
