摘　　要：报道了基于石墨烯可饱和吸收镜的被动调Q锁模光纤激光器。激光器以大模场双包层掺镱光子晶体光纤为增益介质,采用线形腔结构。在抽运功率12 W时,得到了最高115mW的调Q锁模脉冲输出。输出峰值波长1039nm,光谱的半峰全宽为6nm。对实验结果及现象进行了详细的讨论和分析。A passively Q-switched mode-locked fiber laser based on graphene saturable absorber mirror is reported. A large-mode-area double-cladding Yb-doped photonic crystal fiber is adopted as a gain medium and a linear cavity is used. At pump power of 12 W, the maximum output power of 115 mW is obtained and the spectrum is centered at 1039 nm with full width of half maximum of 6 nm. The experimental results and the phenomenon are discussed and analyzed.
