摘　　要：文章主要介绍了用MCVD工艺及溶液掺杂法制备掺Yb3+双包层结构石英光纤的优化设计、原理及制作工艺.制作出Yb3+掺杂浓度高(吸收损耗在976nm时为2～10dB/m)、本底损耗低(在1.3μm时为10dB/km)的掺Yb3+双包层结构石英光纤.The article gave an introduction to the optimun design, principle and fabrication technology of the Yb3+doped doubleclad fiber which is made by MCVD and solution doping technique. This Yb3+doped donbleclad fiber has high doping concentration (the absorption loss is 2～10 dB/m at 976 nm) and low intrinsic loss (10 dB/km at 1.3μm).
