高效率窄线宽掺铒光纤激光器

High Efficiency Narrow Linewidth Er-doped Fiber Laser

在介绍环形腔掺铒光纤激光器原理的基础上,对其功率及其线宽进行了研究,测得的激光光谱3dB带宽及其输出功率分别为0.05nm和45mW,明显高于文献[2]0.1nm和22.66mW的报道,最后分析了铒纤长度与阈值及输出功率的关系。

Narrow linewidth erbium-doped fiber lasers have widespread applications in fiber communication , fiber sensor, spectral measurement ,and so on.In this paper, The principle of erbium-doped fiber laser is introduced. We obtained its output power and the optical spectrum.The values are 45mW and 0.05nm（3dB）. Then we analyzed the outpower of the laser versus the length of the fiber.
