摘要: 为了在光纤激光器中获得具有中心波长可调谐的锁模脉冲输出，采用半导体可饱和吸收镜和Sagnac环作为腔镜，搭建了线性腔掺镱锁模光纤激光器，并进行了实验验证。通过调节泵浦功率和Sagnac环中的偏振控制器，在泵浦功率140 mW保偏光纤长度为18 cm时获得最大的调谐范围输出，输出中心波长从1032.53 nm连续调谐至1043.76 nm，调谐范围为11.23 nm。该研究可以为搭建结构紧凑的可调谐激光器提供设计方案。
Abstract: In order to obtain mode-locked pulse output with tunable central wavelength in fiber lasers, a linear cavity ytterbium doped mode-locked fiber laser was constructed using semiconductor saturable absorption mirrors and Sagnac rings as cavity mirrors, and experimental verification was conducted. By adjusting the pump power and polarization controller in the Sagnac ring, the maximum tuning range output was obtained at a pump power of 140 mW polarization maintaining fiber length of 18 cm. The output center wavelength was continuously tuned from 1032.53 nm to 1043.76 nm, with a tuning range of 11.23 nm. This study can provide a design solution for building compact tunable lasers.
