Coherent beam combining with micro-lens arrays
arXiv:2010.09415 · doi:10.1364/OL.414388
Abstract
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.
