Open publisher page 64 citations

Abstract

An 85 W Tm3+-doped silica fibre laser is presented. To the best of the authors' knowledge this is the highest output power achieved by pumping with 793 nm. The slope efficiency was 56%, the threshold 11 W and the output wavelength centred at 2.04 µm. The high rate of cross relaxation in this laser provided a quantum efficiency of >130%.
