| 摘 要： | 大型激光驱动器装置对光纤前端系统的输出脉冲能力提出了更高的要求,基于大模场光子晶体光纤的mJ级脉冲放大器技术是首先需要解决的关键技术问题。研究了大模场光子晶体的切割和熔接工艺,实现了全光纤结构集成。对1~10kHz重复频率、10ns脉宽、0.3nm线宽的方波脉冲进行了放大实验研究,对比研究了反向和正向泵浦方式对自发辐射放大的抑制效果,在1kHz获得0.6mJ,单横模脉冲输出,初步验证了基于此类系统获得大能量、高品质脉冲输出的能力。

| Abstract: | The cleaving and fusion splicing technology of the large-mode-area photonic crystal fiber was explored to achieve all-fiber structure. The amplification of the pulse with 1-10 kHz repetition rate, 10 ns duration and 0.3 nm line-width was experimentally researched. The suppression effect of the amplified spontaneous emission employing forward and backward pumping method was compared. Fundamental mode, 0.6 mJ pulse was obtained at 1 kHz which demonstrated the technical feasibility of achieving high energy and high quality pulse output from this kind of amplifier. |
