【摘要】论文报道了基于氧化石墨烯可饱和吸收体掺铒光纤锁模激光器的研究.实验过程中将氧化石墨烯分散到PVA醇解物中,制成了氧化石墨烯-PVA薄膜,并将该薄膜作为饱和吸收体应用于掺铒光纤激光器中,实现了稳定的锁模运转.激光脉冲的重复频率为9.26MHz,中心波长为1 531.30nm,3dB带宽为1.38nm,激光脉冲的宽度约为1.78ps.更多还原

【Abstract】 The research of the Er3+doped Fiber Mode-locked Laser based on the graphene oxide was reported.During the experiment,large-scale graphene oxide-PVA(polyvinyl alcohol)film was prepared by dissolving the graphene oxide in the saponified PVA.The film was applied to the Er3+doped fiber laser as a saturable absorber,and stable mode-locked laser was achieved with the pulse frequency of 9.26 MHz,central wavelenth of 1 531.30nm,3dB bandwidth of 1.38nm and the pulse width is about 1.78ps.更多还原
