Description	In this contribution we present numerical study of propagation of the multimode pump radiation in the inner cladding of the developed double-clad fiber. Field evolution was simulated using full vector finite element beam propagation method. Due to reeling of the fiber on the spool, the curvature of the fiber is involved in the model. The longitudinal dependence of power distribution was then analyzed. The simulations showed that after the length of propagation of about 40 mm the field becomes homogeneously distributed in the structure. Over 90 % of pump energy is absorbed in 3 m of the rare-earth-doped fiber with core-absorption of 2000 dB/m and cladding-core diameter ratio of 18.5. This confirms suitability of the tailored cross section for effective pump absorption along the rare-earth-doped fiber In this contribution we present numerical study of propagation of the multimode pump radiation in the inner cladding of the developed double-clad fiber.
