激光冷却铷原子喷泉钟的微波谐振腔设计

对自行研制的激光冷却铷原子喷泉钟的微波谐振腔进行了分析和设计,确定了需要的微波谐振腔基本参数。对影响微波谐振腔共振频率的因素进行了分析和研究,得到了共振频率随环境因素的变化规律。这些对调节微波腔共振频率和提高原子钟的准确度有重要意义。还对研制的微波谐振腔进行了测试,结果表明微波谐振腔的性能满足激光冷却铷原子喷泉钟的要求。由测试结果进一步估算了微波谐振腔引起的横向腔相移。

Design for Microwave Cavity in a Laser-Cooled Rb Fountain Clock

The analysis and design for the microwave cavity in laser-cooled Rb fountain clock developed by ourselves were presented and the basic parameters of the microwave cavity developed were designed in this paper.Based on the analysis to the factors of affecting the resonant frequency of the microwave cavity,the laws of the resonant frequency with surroundings factors were obtained,which are very important significance to improve the accuracy of the atom clock and to adjust the resonant frequency of the microwave cavity.Finally,the microwave cavity developed was tested and the test results indicated that the performance of microwave cavity met the requirements for laser-cooled Rb fountain clock.The transverse phase shift from the microwave cavity was evaluated by the test results.
