Abstract

We observed dissipative soliton resonance phenomenon in a graphene oxide mode-locked Yb-doped fiber laser, which delivered square-shaped pulse of 0.52 ns~60.8 ns and single pulse energy of 159.4 nJ at 1064.9 nm. The 3 dB-bandwidth of Lorentz-shaped spectrum was 0.19 nm. We pointed out that the reverse saturable absorption played a big role in generating square-shaped or flat-top pulses, which verified by additional simulation work.

摘要

我们在氧化石墨烯锁模掺镱光纤激光器中观测到了耗散孤子共振现象，该激光器在1064.9 nm波长处输出脉宽为0.52 ns至60.8 ns的方形脉冲，单脉冲能量为159.4 nJ。洛伦兹形状光谱的3 dB带宽为0.19 nm。我们指出，反向饱和吸收在产生方形或平顶脉冲中起了很大作用，这一点通过额外的模拟工作得到了验证。
