High-power continuous wave erbium-doped fiber laser pumped by a 1480-nm Raman fiber laser

摘要

We present a high power Er-doped fiber laser operating at 1555 nm, core pumped by a Raman fiber laser operating at 1480 nm. We achieve 55 W total output power for 67 W of pump power with a slope efficiency of 81%. To the best of our knowledge, this is the
