【摘要】 报告了实现钙原子光频标的前期工作—钙原子束的光学Ramsey谱线研究的初步工作,介绍了实验的系统方案、真空和激光器部分的设计以及部分已完成的工作。在得到光学Ramsey线形后,如果把激光器锁定在谱线上,就可以得到一个高精度的光学频率标准。更多还原

【Abstract】 The preliminary work on optical Ramsey spectroscopy,which is the first step to accomplish a calcium optical frequency standard,is reported.The system scheme of this experiment,the design of vacuum setup and laser system,and some completed work are described.An optical frequency standard with high precision can be obtained if the laser frequency is locked to the Ramsey fringe.更多还原
