Abstract

We present the method of bismuth active centers concentration evaluation based on determination of ultimate pulse energy from Bi-doped fibers and measurements of their radial distribution in fiber preform. The values of average concentration of active centers and overlap integral with fundamental mode for phosphosilicate fibers with bismuth were evaluated.
