Abstract
In the paper design and experimental study on manufacturing 8 - core double- clad optical fiber doped with Nd3+ were presented. Basing on ray tracing model the analysis of pumping efficiency in the 8 - core double - clad optical fiber was performed. The influence of constructional parameters of optical fiber on the laser beam quality of multicore fiber laser was analyzed. I was noticed that pumping efficiency of the fabricated 8 - core optical fiber is several times larger than in single core double – clad optical fiber. The maximum absorption at 808 nm band amounts to 4.5 dB/m. Manufactured multicore fiber doped with Nd3+ is characterized by strong luminescence at 1060 nm. In result of pump absorption optimization enhancement of pumping efficiency of produced 8- core double - clad optical fiber was attained.
