摘要
利用光纤环形镜对脉冲进行压缩有着消除脉冲基座的优势而被广泛采用。传统的色散递减光纤构成的环形腔构成都采用50∶50的耦合器,本文通过对不同脉冲宽度及不同类型色散递减光纤构成的环形腔镜研究,分析发现采用60∶40的非等比耦合器较50∶50的耦合器构成的环形腔镜能够获得更高压缩质量的输出脉冲。
It is widely used to compress pulse by using fiber loop mirror to eliminate pulse pedestal. The fiber loop mirror conventional consists of a dispersion decreasing fiber adopting 50 ∶50(3 dB) coupler. In this paper,through the study of the fiber loop mirror composed of different pulse width and different types of dispersion decreasing fiber,it is found that the output pulse of higher compression quality can be obtained by using the non-uniform coupler of 60 ∶40 than that of 50 ∶50.
