本文讨论了Ho:YAG激光在细纤芯光纤传输的最佳方式.研究了耦合透镜、入射光斑、发散角之间的相互影响和最佳匹配方法;讨论了激光器的设计中,激光棒的热透镜效应对系统参数的影响,提出了修正方法,推导出了相应的修正公式;并通过实验对理论研究进行了验证.

In this paper, a method is introduced for Ho:YAG laser transmission in thin fiber. Effects and the best match method are studied about interface lens, facula, and divergent angle of Ho:YAG laser. The impact of heating of rod on system parameter is discussed, correction method has been proposed, and correction formula is inferred. The experimental rasults are in accordance with the theory.
