掺镱PCF的端面处理工艺及激光性能研究(特邀)

Study on end treatment process and laser performance of Yb doped PCF (Invited)

  • 摘要: 基于自制的掺镱大模场光子晶体光纤,探索出一种高效快速的光子晶体光纤端面处理工艺。使用二氧化碳激光熔接机对光子晶体光纤进行旋转加热处理,并配合大口径光纤切割刀对塌缩区域进行切割。通过对比光纤在不同激光加热功率和加热时间下的塌缩效果,确定了最佳的加热功率和时间。对端面处理后的光纤进行激光震荡实验,测试光纤的激光性能,与未进行端面处理时的激光实验结果相比较,端面塌缩处理没有对光纤的激光性能产生较大的影响。通过所述的实验方法,成功得到高质量光子晶体光纤塌缩端面,空气孔塌缩界面齐整,且没有对光纤本身的激光性能产生较大的影响。实验工艺周期短、成功率高,证明利用激光加热塌缩来处理光子晶体光纤端面是一种非常有效的方法,极大地拓展了光子晶体光纤的使用范围,具有很强的实用价值。

     

    Abstract: An efficient and fast processing technology of photonic crystal fiber (PCF) end face based on the homemade Ytterbium (Yb) doped large mode area (LMA) PCF was demonstrated. By using carbon dioxide laser splicer, the PCF was rotated and laser heated at the same time. The optimal heating power and time were determined by comparing the collapse effect of the fiber under different laser heating power and heating time. For examining the optical fiber treated, the fiber laser system was built. The experiment results indicate that the collapse of the end face does not have a great influence on the laser properties of the fiber when it is compared with laser experiments without end processing results. High quality PCF collapse face can be achieved by the experimental method described, the air holes collapsed boundary are neat and uniform, meanwhile the influence of the collapse treated on the laser properties of the optical fiber is not obvious. The experimental process is short and the success rate is high, which proves that it is an effective method to deal with the end face of PCF by laser heating collapse, greatly expands the use range of the PCF, and has very strong practical value.
