摘　　要：以双包层掺镱光纤为增益介质，双折射滤光片为波长选择器件，搭建了可调谐耗散孤子锁模光纤激光器。通过旋转滤光片，激光器的输出波长在1063．9～1091．1nm范围内连续可调，脉冲宽度及光谱带宽的变化范围分别为13．9-16．8ps和15．8～18nm。中心波长为1063．9nm时，激光器输出功率为212mw，单脉冲能量为8．5nJ。基于耦合的Ginzburg-Landau方程和各器件的琼斯矩阵，建立了可调谐耗散孤子锁模激光器的数值模型，对激光器的可调谐性能进行模拟，模拟结果与实验结果一致。A wavelength tunable, passively mode-locked Yb-doped double-clad fiber laser with a birefringent filter is demonstrated in this paper. By carefully rotating the filter, the central wavelength of the mode-locked fiber laser can be continuously tuned from 1063.9 nm to 1091. 1 nm. The pulse duration ranges from 13.9 ps to 16.8 ps, and spectrum width varies between 15.8 nm and 18 nm. The maximum average output power of 212 mW is obtained at the central wavelength of 1063.9 nm. The corresponding pulse energy is 8.5 nJ. A theoretical model is established based on the coupled Ginzburg-Landau equations and Jones matrices. Simulation results agree with the experimental results.
