  A novel concept for dynamic focus shaping based on highly efficient coherent
beam combining with microlens arrays (MLA) as combining element is presented.
This concept allows to control the power weights of diffraction orders by
varying the absolute phases of an array of input beams. A proof-of-principle
experiment is supported by simulations. For this, an input beam matrix of 5 x 5
beams is combined proving both the ability for further power scaling and
dynamic focus shaping.
