Abstract

We report on a low-threshold efficient yellow Dy-fiber laser with good beam quality featuring high-brightness pumping. It employs a single-clad 0.2 mol% Dy:ZBLAN fiber pumped by two 450-nm blue GaN laser diodes. The continuous-wave Dy-fiber laser delivers a maximum output power of 109 mW at 575 nm with a laser threshold of 218 mW, a slope efficiency of 19.6%, and beam quality factors M ∼ 1.5. The overall optical efficiency versus incident pump power is 13.9%, being record-high, to the best of our knowledge, for this type of laser. The laser performance is simulated based on the spectroscopic data, being in good agreement with the experiment.

摘要

我们报道了一种具有良好光束质量、采用高亮度泵浦的低阈值高效黄色镝光纤激光器。它采用一根掺杂0.2 mol%镝的单包层ZBLAN光纤，由两个450纳米的蓝色氮化镓激光二极管泵浦。连续波镝光纤激光器在575纳米处的最大输出功率为109 毫瓦，激光阈值为218 毫瓦，斜率效率为19.6%，光束质量因子M约为1.5。据我们所知，相对于入射泵浦功率的整体光效率为13.9%，创该类激光器的最高纪录。基于光谱数据对激光性能进行了模拟，与实验结果吻合良好。
