Tunable Grating External-cavity Yb3+ Double-cladding Fiber Laser with Littman Set-up
摘要
本文对LD泵浦的光栅外腔可调谐双包层Yb3+光纤激光器进行了实验研究.采用Littman外腔结构,研究了Yb3+光纤激光器的调谐特性.输出激光调谐范围42 nm,谱线宽度0.08 nm,最大输出功率达到了460 mW,斜率效率约30%.并对其输出光功率随波长的变化进行了观测和分析.
Abstract
A study on a tunable fiber laser is presented in this paper. A twenty-meter-long double-cladding Yb3+-doped fiber laser which tuning range is 42 nm in Littman configuration and line width is less than 0.06 nm is pumped by a high-power multimode LD system. The output power is up to 460 mW, and the slope efficiency is about 30%. The optimization of high-power tunable fiber lasers is discussed.
