We demonstrate an all-fiber-based photonic microwave generation with 10-15frequency instability.The system consists of an ultra-stable laser by optical fiber delay line,an all-fiber-based"figure-of-nine"optical frequency comb,a high signal-tonoise ratio photonic detection unit,and a microwave frequency synthesizer.The whole optical links are made from optical fiber and optical fiber components,which renders the whole system compactness,reliability,and robustness with respect to enviro... 相似文献

基于未来卫星间激光干涉任务的需求,介绍了一种基于迈克耳孙光纤干涉仪稳频的1064 nm激光稳频系统,该系统采用全光纤器件,结构紧凑、体积小、可靠性强。通过拍频测试,得到该系统的频率噪声在30 mHz~1 Hz范围内小于30 Hz/Hz1/2,频率稳定度在积分时间为1 s和1000 s时分别为1.2×10-14和3×10-13。该系统的性能满足LISA任务对稳频激光的需求,有望应用于未来的空间引力波探测任务。 相似文献
