摘要：

The first all-OVD, all-glass, high-NA (greater than or equal to0.3), double-clad Yb-doped laser fibres are reported. Yb is incorporated via vapour-phase transport. These fibres yield low, passive loss (<3/10 dB/km in core/innerclad a 1310nm) and high-conversion efficiency, suitable for power scaling and higher reliability. Fibre lasers with output power of 110 W, M-2 similar or equal to 1.07 and slope efficiency near 80% have been demonstrated.
