title: Coherent combining efficiency in tiled and filled aperture approaches.
abstract: Different approaches to qualify coherent beam combining performance in tiled and filled aperture combining experiments are discussed. The dependence of the combining efficiency on different misalignments and the number of combining pulses has been investigated and analytical equations for its evaluation have been obtained. The results provide design guidelines for laser systems based on coherent beam combining and allow comparison of experiments performed in different combining approaches. The analysis shows that there are good prospects to scale achieved peak intensity.
