双光栅外腔可调谐掺Yb^(3+)双包层光纤激光器

Tunable Yb^(3+)-doped Double-cladding Fiber Laser with a Double-grating Configuration

采用一种新颖的双光栅装置作为外腔调谐结构 ,实现了掺Yb3+ 双包层光纤激光器的调谐输出 ,调谐范围10 37～ 110 6nm。双光栅结构的应用 ,使调谐输出的激光光谱的线宽大大变窄 ,小于 0 1nm。检偏器测量结果表明 ,整个调谐范围内的激光输出均为线偏振光。

Using a novel double-grating arrangement, a tunable Yb3+-doped double-cladding fiber laser with a tuning range from 1037 nm to 1106 nm has been demonstrated. Because of the double-grating arrangement, the bandwidth of every tuned laser is greatly narrowed to less than 0.1 nm, and the output laser is linearly polarized light.
