| 摘 要： | A Tm^3 -doped ZrF4-BaF2-LaF3 AlF3-NaF (ZBLAN) fibre up-conversion laser pumped by a 1120-nm Raman fibre laser is demonstrated with blue output power levels up to 116mW. For the output mirror with 80^ reflectivity, the slope efficiency is about 15%, the optical-to-optical conversion efficiency is 11%, and the maximum un-saturated output power is 116mW. For 60% reflectivity, the slope efficiency is about 18% and the opticalto-optical conversion efficiency is 12%, whilst the maximum saturated output power is about 80roW due to the existence of photo-degradation effect in Tm^3 doped ZBLAN glass fibre.
