Influence of beam shape on piston and tilt error in coherent combined laser array [PDF]

open access: yesOptical Engineering, 2019
An analysis of beam combining quality and the influence of beam profile on tilt and piston error tolerances is presented. We define beam combining performance metrics in terms of powers contained within a specific radius. It is shown that the selection of this radius has a significant effect on the obtained tolerance values. We have taken the tolerance
