Abstract :
A highly efficient cladding-pumped erbium/ytterbium-doped large-core fibre amplifier, generating up to 87 W of single-frequency continuous-wave output at 1563 nm, with a good beam quality (M2≤1.7), in a master oscillator power amplifier configuration is reported. The overall optical power conversion efficiency was 26%.
