摘　　要：从光纤端面的不同处理方法(抛磨法、切割法)入手,对各自工艺展开了较深入的探索,测试了经不同方法处理后光纤端面的表面粗糙度:抛磨端面的表面粗糙度达到0.6nm,切割端面的表面粗糙度为24nm。研究了不同端面处理方法对光纤激光器输出性能(输出功率、光束质量)的影响。The difference of the two methods of fiber facet handling was discussed.We tested the Ra of the facet after polishing or cleaving the fiber facet.The Ra of the polished facet was 0.6nm,though the Ra of the facet was only 24nm.The influence of the fiber facet on the output power and beam quality of fiber lasers was also researched.
