Coherent beam combining with micro-lens arrays

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...

Zusammenfassung: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.
