Paper Abstract

In the paper the conditions of applying multicore (5 - core and 30 - core) optical fibers for the phase - locked fiber laser systems were analyzed. The influence of parameters of the active multicore optical fibre and phase deviation on the beam quality factor of the fibre laser beam in the far - field diffraction region has been determined. Based on proposed model of supermode generation in multicore fiber laser, the influence of evanescent wave coupling between the cores (in 5- core and 30 - core fibres) on the difference in radiation phases between particular emitters during the development of the laser action was considered calculated. The luminescence spectra of the fabricated, in accordance with designated parameters, 5 - core and 30 - core double clad multicore optical fibres doped with Nd3+ were presented. Measured far-field pattern of the fabricated Nd3+doped 5-core optical fiber consists of a high intensity central peak and side lobes. It indicates that phase - locking effect in presented optical fiber was achieved.
