Quantum efficiency and background loss in low thulium concentration silica fibres
Quantum efficiency and background loss in low thulium concentration silica fibres
The influence of low thulium concentration in silica fibre on the two-for-one cross-relaxation process and background propagation loss was studied. A two-for-one cross-relaxation process (quantum efficiency 1.18) was observed even in 0.2 wt.% thulium-doped fibre.
