摘要：
Results are presented on a 1064nm upconversion pumped thulium doped fluoride fibre laser operating on the F-3(4) - H-3(4) transition around 1.47mum. A minimum threshold of 8.7mW (3.6mW absorbed), and a maximum slope efficiency of 58% (80% photon conversion efficiency), with respect to launched pump power has been observed. In addition a maximum gain efficiency of 0.22dB/mW has been demonstrated.
