In the paper, the phase-locked emitters in multi-core optical fibres for high power fibre lasers are presented. The influence of the normalized frequency and diameters of the cores on the shape of the pattern in the Fraunhofer diffraction region has been analysed. The simulation of coupling coefficient between cores influences on phase-locking and in the consequence on the far-field pattern of the fibre laser, based on the analyzed multi-core optical fibre, were performed. In the analyzed fibre laser, while exchanging power of the generated radiation between two adjacent cores on the fibre length (L = 5 m) within the range of 4-10%, the radiation becomes phased. Having satisfied this condition, in the far-field low-divergence, high-power laser beam (supermode) is attained. 5-core double clad optical fibre doped with neodymium ions was fabricated. Luminescence spectra of the manufactured fibre were measured.
