中文摘要：
本文报道了国内自行研制和制备的以高功率光子晶体光纤激光器为目标的Yb^3＋掺杂双包层光子晶体光纤。给出了Yb^3＋掺杂多组分玻璃芯棒和以此为芯的双包层光子晶诛光纤的制备流程、工艺和关键技术。对制备的Yb^3＋掺杂多组分玻璃、双包层光子晶体光纤进行一系列的物理属性、热学和光谱测试，并通过计算分析得到相对优秀的掺杂多组分玻璃配方（Yb^3＋-（2mol％）-SiO2（70mol％）-MgO-CaO-BaO-Li2O-Al2fO3（2mol％））。样品中的Yb^3＋掺杂双包层光子晶体光纤具有结构规则传光性能良好等优点，为自行开发高功率光子晶体光纤激光器提供材料器件基础。
英文摘要：
The paper reports homemade Yb^3＋ doped double-clad photonie crystal fiber for high power fiber laser, and gives the preparation process, pivotal technology and critical technology of a multi-component glass Yb^3＋ doping, from which the core of the double clad photonic crystal fiber is made. The fabricated Yb^3＋ doped multi-component glass and double clad photonic crystal fiber are tested by a series of physical properties, thermal and spectral experiments. The result of calculation of multi-component doped glass shows appropriate quality （Yb^3＋-（2mol%）-SiO2 （70mol%）-MgO- CaO-BaO-Li2O-Al2O3（2mol%））, and good double clad structure of a photonic crystal fiber and optical properties to provide material basis for, China＇s self-developed high power photonic crystal fiber laser devices.
