The performed combiner, with pump power of 80–85% transmission level, was successfully applied in a thulium doped fibre laser. The performed all-fibre laser setup reached a total CW output power of 6.42 W, achieving the efficiency on a 32.1% level}, type={Article}, title={High-power pump combiners for Tm-doped fibre lasers}, URL={http://journals.pan.pl/Content/116148/PDF/opelre_2015_33.pdf}, keywords={fibre lasers, thulium-doped fibres, pump power combiners, tapered fibre bundles}, }
