Abstract

Cladding pumped erbium-ytterbium fiber lasers (EYDFL) in different free-running configurations have been described. We obtained slope efficiency of up to 50% with respect to absorbed pump power and an output power of 16.8 W.We study the influence of fiber length and pump wavelength in cladding-pumped erbium-ytterbium doped fiber lasers. We reached up to 16.8 W of output power from an EYDFL pumped through both ends at 915 nm. We believe this to be the highest-power EYDFL described in the literature. The slope efficiency was up to 50% with 915 nm pumping and 38% with 980 nm pumping,, both with respect to absorbed pump power.
