摘要

利用随机光纤激光器结构对产生覆盖可见光至近红外波段的超连续谱进行了研究。实验采用半开腔的随机激光腔体结构,腔内利用千米量级的掺锗光纤提供随机分布反馈和拉曼增益,同时利用掺镱光纤提供主动增益,最终实现了光谱范围覆盖600~1700 nm、同时20 dB光谱带宽大于660 nm的超连续谱输出。实验结果表明,随机光纤激光器作为一种新型超连续谱光源,可用于多种对稳健性和性价比有较高要求的应用场合。

Abstract

We investigate visible to near-infrared supercontinuum generated by random fiber laser structure. Half-opened cavity random fiber laser is established, using germanium-doped fiber with several kilo-meters to provide random distributed feedback and Raman gain and ytterbium-doped fiber to supply active gain. Supercontinuum covering 600-1700 nm with 20 dB bandwidth of more than 660 nm is achieved. It shows that random fiber laser can be a novel supercontinuum source, which can be utilized to many applications where high robustness and low cost are required.
