The paper reports homemade Yb³⁺ doped double-clad photonic crystal fiber for high power fiber laser, and gives the preparation process, pivotal technology and critical technology of a multi-component glass Yb³⁺ doping, from which the core of the double clad photonic crystal fiber is made. The fabricated Yb³⁺ 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 (Yb³⁺-(2mol%)-SiO₂ (70mol%)-MgOCaO-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.
