摘　　要：利用自行研制的大模面积双包层光纤和光学耦合系统以及国产的 LD 泵源,研制开发出一种便携式掺 Yb^(3+)双包层光纤激光器,最大激光输出功率达到了12.73w,斜率效率为76.9%,激光器的光-光转换效率为45%.实现了全国产化的、高功率、高转换效率的稳定激光输出,而且具有较高的光束质量,给出了该激光器的实验结果,并对其主要特性进行了简要的分析。Using large-mode-area double cladding fiber,optically coupled system （both researched by our own） and homemade LD pump,a type of portable Yb^3＋-doped double-cladding fiber laser is developed. Its maximum output power of laser is 12. 73 W, slope efficiency is 76.9%, and light-light transfer efficiency is 45%. And a completely homemade stable laser has been realized with high-power, high-conversion-efficiency and higher light beam quality. The experimental results of laser and the briefly analysis of its primary characteristics are given.
