摘要
以波分复用器(WDM),光纤光栅和自行研制的掺Yb^(3+)单模光纤,采用新颖的全光纤连接方案,实现了1060nm窄线宽、线形腔激光器的成功运转。对不同长度掺镱光纤(YDF)所构成的激光器进行了实验研究,发现9m为最佳长度。入纤抽运阈值功率约为30mW,当入纤功率达到最大值42.8mW时,得到最大激光输出8.8mW,半宽<0.5nm,相对于入纤抽运功率的斜率效率为70.4％。
Using a novel, all-fiber structure composed of WDM, fiber grating and domestic-made Yb-doped single-mode fiber, the F-P cavity laser operating at 1060 nm with narrow-FWHM is realized. Optimal length to be 9 m are found through the experiment for different length of the YDF. The threshold of launched pump power is 30 mW. When launched pump power is 42.8 mW, the maximum laser output is 8.8 mW with a FWHM<0.5 nm. The slope efficiency is 70.4% with respect to the launched pump power.
