Abstract :
The fiber laser containing 7-core hexagonal structure doped by Yb was suggested and experimentally studied in ref. [1]. It was observed that the pattern in the far field at more than 100 W laser power looks like that of the in-phase mode of the structure. Numerical simulations based on 3D Beam Propagation Method (BPM) in have demonstrated that the effect observed in is associated with filtering by spatial configuration of gain in the cores.
