摘　　要：A ytterbium-doped double-clad fiber laser with more than 50-W output, near diffraction-limited is demonstrated in SIOM. The optical-to-optical efficiency is about 44% with respect to incident pump power and the slope efficiency is 69% against launched pump power.A ytterbium-doped double-clad fiber laser with more than 50-W output, near diffraction-limited is demonstrated in SIOM.
