摘要
本工作采用溶液掺杂的气相沉积工艺制备钕、铒掺杂石英光纤,进行了掺杂工艺、掺杂浓度,光纤结构和损耗等基础研究,试制的钕光纤吸收带损耗a_(810nm)=5.4×10~4db/Km,发光带损耗a_(1.08)=100db/Km,光纤中Nd^(3+)离子含量约为2700ppm。铒光纤在670nm和1540nm波长处的损耗约为10~4db/Km,Er^(3+)离子浓度约2900ppm。
We here report a solution-doping MCVD technique for the fabrication of Nd or Er ions doped silica op- tical fibres, We have studied the doping technique, ions concentration, fibre stracture and attenuation spectra, The optical fibers containing ~2700ppm of Nd^(3+)ions, its loss are α_(810nm)= 5.4×10~4db/Km at the absorption band and α1.08μm= 100db/Km at the emission band. the loss of the fibre containing about 2900ppm of Er^(3+)ions which are ~10~4db / km at the 670nm and 1.54nm wavelenth.
