摘      要：An ytterbium-doped double-clad fiber laser with one-end pumped by four 915 nm laser diodes(LDs) combined by a homemade multimode fused fiber bundle combiner is proposed. The combiner, fused by splicing four fiber pigtails from diodes, exhibits a good capability of low-loss and a high efficiency of 92.7%.The fiber laser, which can generate a continuous-wave(CW) up to 10.3 W output power at 1104 nm with a homemade D-shape inner cladding ytterbium-doped fiber, is demonstrated. The slope efficiency is about65% and the optical-to-optical conversion efficiency with respect to the pump power is 46% at its maximum output laser power.
