| 摘 要： | 报道了基于氧化石墨烯的被动调Q掺铒光纤激光器。激光器采用环形腔结构，调Q器件为自制的氧化石墨烯可饱和吸收镜。泵浦功率在81~505 mW范围内时，得到了重复频率68~124 kHz的稳定的调Q脉冲输出，脉宽为0.47~1.60 s。由于泵浦功率限制，激光器最大输出功率为10 mW, 相应单脉冲能量为80.6 nJ。此种基于氧化石墨烯可饱和吸收体的被动调Q光纤激光器体积小、成本低廉、结构简单、稳定性高、光束质量高，具有广阔的应用前景。

| Abstract: | The graphene-oxide-based passively Q-switched erbium-doped fiber laser is first reported. The laser adopts ring cavity configuration, and the Q-switcher is the self-made graphene oxide saturable absorber mirror. Stable Q-switched pulses with the frequency of 68~124 kHz and pulse width of 0.47~1.6 μs are output at 80~505 mW incident pump power. Limited by the pump power, the maximum output power is 10 mW, corresponding to the single pulse energy of 80.6 nJ. This kind of new Q-switched fiber laser with graphene oxide as the saturable absorber will have great applications, due to its advantages of low price, simple design and high stability.Key words: |
