| 摘 要： | 窄线宽激光器在铯原子喷泉钟、光钟以及时间频率传递等方面有着重要的作用。主要介绍中国科学院国家授时中心开展的工作波长为698 nm窄线宽激光器的研究进展。实验中采用两级稳频方法将激光锁到初稳腔和高稳腔。通过第一级稳频,激光线宽为1.1 kHz;目前已初步实现了第二级稳频。通过逐渐优化第二级稳频,可以实现Hz量级线宽激光。 |
| 关 键 词： | 锶原子光晶格钟 窄线宽激光器 高精度时间频率 激光稳频 |

| Abstract: | Narrow-linewidth laser plays an important role in Cs atomic fountain clock and optical clock as well as time and frequency transfer.We mainly introduce the progress of the research on narrow-linewidth laser at 698 nm in the National Time Service Centre.The two-steps stabilization for laser frequency is adopted to lock the laser on the pre-cavity and ultra-stable cavity in our experiment.Presently,the laser linewidth is around 1.1 kHz with the first stabilization,while the laser locking in the second stabilization is preliminarily achieved.A Hz-level laser is expected by gradually improving the second stabilization. |
| Keywords: | Sr optical lattice clock narrow-linewidth laser high-accuracy time and frequency laser frequency stabilization |
