摘　　要：报道了溶液掺杂法制备Er-Yb共掺双包层光纤的技术.采用改进的化学汽相沉积研制工艺,制作了SiO2-P2O5-F的光纤阻挡层和SiO2-GeO2-P2O5的疏松芯层,利用疏松芯层在YbCl3、ErCl3溶液中的浸泡吸收作用,成功研制出Er、Yb离子浓度比分别为1∶13和1∶8两个光纤样品,其中样品2在976nm泵浦波长处的有效吸收系数最大达到2dB/m,分析和讨论了光纤的损耗谱和荧光特性.The MCVD and solution-doping technology for the Er-Yb co-doped double-clad fiber was reported. Using the MCVD manufacture technics,the fiber isolation layers（SiO2-P2O5-F） and the porous frits（SiO2 GeO2-P2O5） were deposited. The porous frits were soaked in the solutions of YbCl3 and ErCl3. Two fiber samples with 1 ： 13 and 1 ： 8 of Molar ratio Er/Yb were fabricated respectively. The maximium effective absorption coefficient of the sample 2 at the pump wavelengh 976 nm is 2 dB/m. The attenuation spectral and fluorescence characteristic were discussed.
