论文摘要
通过相锁的纤维激光器实现了用于原子干涉测量法的低噪声激光系统，其中FEOM反馈回路和狭窄的线宽大大提高了OPLL的性能。激光系统证明，每次射击贡献2.2 mrad对干涉仪噪声，并允许在现场测试中进行超过115小时的持续长期操作超过115小时。同样，配备这种相锁激光系统的移动重量表达到的灵敏度高达29 ugal/\ sqrt {Hz}，在1500 s内的分辨率为1.1 ugal，表明性能与艺术状态相当。
A low noise laser system for atom interferometry is realized with phase-locked fiber lasers, where the performance of the OPLL is greatly enhanced by the FEOM feedback loop and the narrow linewidths. The laser system demonstrated contribute 2.2 mrad per shot to the interferometer noise and permit continuous long-term operation for more than 115 hours without relocking in the field test. Also, the mobile gravimeter equipped with this phase-locked laser system reaches a sensitivity as good as 29 uGal/\sqrt{Hz} and a resolution of 1.1 uGal within 1500 s, demonstrating performances comparable to the state of the art.
