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 technology of preparing Er-Yb co-doped double-clad fiber by solution doping was reported.The optical fiber barrier of SiO2-P2O5-F and the loose core of SiO2-GeO2-P2O5 were prepared by the improved chemical vapor deposition , Two optical fiber samples with Er and Yb ion concentration ratios of 1:13 and 1:8 were successfully developed by using the soaking and absorbing effect of the loose core in YbCl3 and ErCl3 solution. Sample 2 was effective at 976 nm pump wavelength Absorption coefficient up to 2dB / m, analysis and discussion of the fiber loss spectrum and fluorescence characteristics.
