Abstract

Cladding pumping is now a well established technique for power scaling fibre lasers and amplifiers. For early work on cladding pumped Er3+/Yb3+ amplifier1, however, the efficiency was much lower than that of double clad Er3+ fibre amplifier. Here we demonstrate an efficient Er3+/Yb3+ co-doped double-clad fibre with efficiency over 40%. Bending effect in cladding pumping scheme is also discussed.
