### [PDF] Dynamic coherent beam combining based on a .. - Semantic Scholar

A novel optical concept is introduced with standard components for highly efficient coherent beam combining a system of (N x N) beams.. In a proof-of-principle experiment a well-defined setup with microlens arrays (MLAs) is used to create a beam matrix of 5 x 5 beams.. For the combination step the same setup is employed, and the created 25 beams are combined.. A combination efficiency above 90% ..
