103 W Erbium/ytterbium co-doped large-core fiber laser
We report a highly efficient cladding-pumped erbium–ytterbium co-doped large-core fiber laser, generating up to 103W of continuous-wave output power at 1.57µm with a beam quality (M2) of 2.0. The overall slope efficiency was 30% (40% at low powers) with respect to the launched pump power. A roll-off in output power was observed at higher powers caused by the onset of co-lasing at ~1.06µm due to the increased ytterbium-excitation at high pump powers. Our result highlights the impressive power capacity of erbium–ytterbium co-doped fibers.

Abstract

We report a highly efficient cladding-pumped erbium–ytterbium co-doped large-core fiber laser, generating up to 103W of continuous-wave output power at 1.57µm with a beam quality (M2) of 2.0. The overall slope efficiency was 30% (40% at low powers) with respect to the launched pump power. A roll-off in output power was observed at higher powers caused by the onset of co-lasing at ~1.06µm due to the increased ytterbium-excitation at high pump powers. Our result highlights the impressive power capacity of erbium–ytterbium co-doped fibers.
