Abstract

We demonstrate a cascaded Raman fiber laser with a record output power of 104 W at 1480 nm. We achieve this with an 1117 nm Yb-doped fiber laser pumping a cascaded Raman conversion to 1480nm. Enhanced efficiency is achieved in the Raman cavity using a fiber with a long wavelength cut-off which prevents further Raman conversion of 1480 nm light and thus allowing for longer cavity lengths. The output is single mode making it a bright source for core or cladding pumping of erbium-doped fiber lasers.
