A Yb:YAG-derived silica fiber was fabricated by a molten-core fabrication method, in which a Yb:YAG crystal was used as the core material and a silica tube was used as the cladding material. The fiber's transmission loss was measured to be 0.49 dB/m at 1.55 µm, using a cut-back method. The fiber microstructure image showed that the cladding region was a uniform glass structure, while the core structure was amorphous. An all-fiber-integrated cladding-pumped laser based on Yb:YAG-derived silica fiber was demonstrated. With an incident pump power of 28 W, an output power of 6 W was obtained at 1.06 μm, with a slope efficiency of 21.7%.
采用熔芯法制备了一种掺镱钇铝石榴石（Yb:YAG）衍生的石英光纤，其中以Yb:YAG晶体作为纤芯材料，石英管作为包层材料。采用截断法测得该光纤在1.55μm波长处的传输损耗为0.49dB/m。光纤微观结构图像显示，包层区域为均匀的玻璃结构，而纤芯结构为非晶态。展示了一种基于Yb:YAG衍生石英光纤的全光纤集成包层泵浦激光器。当泵浦光入射功率为28W时，在1.06μm波长处获得了6W的输出功率，斜率效率为21.7%。
