摘要
阐述了国内外在光子暗化效应测试、抗光子暗化性能提升及机理方面的研究工作。展示了测试的光子暗化效应对吸收光谱、特定波长附加损耗以及输出功率的影响。制备的一种新型抗光子暗化光纤,其抗光子暗化性能相对于常规掺镱光纤提升近15倍,斜率效率为81.8%。由此光纤制备的光纤激光器实现800W功率的稳定输出,未观测到功率的衰减。
The researches on the measurement,performance improvement and the mechanism of photo-darkening both in china and abroad are reported in this paper.The photo-darkening effect on the absorption spectra,excess losses at a special wavelength and the fluorescence output power is showed.A new photo-darkening resistance fiber is manufactured.The performance of the photo-darkening resistance improved as a factor of 15,compared with the normal Yb doped silica fiber,and the slope efficiency is 81.8%.An 800 Wfiber laser prepared by the new fiber is realized,and the power decay is not observed.
