Abstract

Coherent combination is established as a power-scaling concept for all kinds of laser architectures from fiber amplifiers to OPCPA systems. It has been demonstrated that it can be used to overcome physical limitations of the single amplifiers [1]. However, in current state-of-the-art systems, cascaded 1:2 beamsplitter setups are used for the beam-splitting and combination, requiring a large number of components when increasing the number of channels. Additionally, the same amplifiers designs as for single channel systems are used.
