| 摘 要： | 放大的自发辐射(ASE)是影响掺Yb3+光纤放大器效率的重要因素之一。为了抑制ASE,本文从放大器的泵浦方式着手,设计并搭建了同步脉冲泵浦的掺Yb3+双包层光纤放大器,证实了其具有明显抑制ASE的效果。在重复率400 Hz时,将平均功率15 mW,脉宽500 ns的信号光放大至170 mW,实现增益10.5 dB。同时实验研究了不同泵浦脉宽对于ASE生成的影响。

| Abstract: | Amplified spontaneous emission(ASE)is one of the most important factors that reduce the fiber amplifier′s efficiency.In order to restrain ASE,a synchronously pulse-pumped Yb-doped double-clad fiber amplifier is designed,which is proven to have significant effect of reducing the power of ASE.At a repetition of 400 Hz,the power of the signal with pulse duration of 500 ns and average power of 15 mW,is up to 170 mW and a gain of 10.5 dB is obtained.Meanwhile,the impact of different pulse width on the ASE has also been studied. |
