提出了一种利用还原氧化石墨烯（rGO）与光子晶体光纤（PCF）超弱相互作用实现功率级、全光纤、超快Er/Yb共掺双包层光纤激光器锁模的方案。将rGO溶液填充到PCF的包层孔中，蒸发后，rGO薄片，贡献可饱和吸收和高非线性，与PCF中心的光强度的1/107相互作用。这种超弱相互作用结构可以提高锁模激光器的热损伤阈值，降低累积非线性，是高功率锁模激光器的理想选择。通过在Er/Yb共掺光纤环形腔中引入可饱和吸收体，获得了飞秒量级的稳定孤子激光输出，并在提高泵浦强度时实现了谐波锁模。最大平均功率为1.14 W。据我们所知，该报告是直接从以基横模运行的全光纤石墨烯锁模激光系统中获得的最高功率。此外，实验结果表明，我们提出的结构是有效的，在产生高功率脉冲时，使用一些其他材料，包括但不限于氧化石墨烯，碳纳米管，拓扑绝缘体，或金属纳米粒子。
We propose a Watt-level, all-fiber, ultrafast Er/Yb-codoped double-clad fiber laser mode-locked by reduced graphene oxide (rGO) interacting with photonic crystal fiber (PCF) ultraweakly. The rGO solution is filled into the cladding holes of PCF, and after evaporation, the rGO flakes, contributing saturable absorption and high nonlinearity, interact with a light intensity of only 1/107 of that in the center of PCF. This ultraweakly interacting structure can enhance the thermal damage threshold and decrease the accumulated nonlinearity, which is proved to be an excellent choice for high-power mode-locked laser. By incorporating the saturable absorber into an Er/Yb-codoped fiber ring cavity, stable soliton laser with femtosecond duration is generated, and harmonic mode-locking is formed when increasing pump strength. The maximum average power of 1.14 W is obtained. To the best of our knowledge, this report is the highest power obtained directly from an all-fiber, graphene-mode-locked laser system operating with fundamental transverse mode. In addition, the experimental results demonstrate that our proposed structure is effective in generating high-power pulses when some other materials are used, including but not limited to graphene oxide, carbon nanotubes, topological insulator, or metal nanoparticles.
