摘要: 本文报导一种新型的、使用光电离检测的Cs原子共振滤波方案.理论算得:原子系统固有的响应时间为10ns,线宽62MHz,量子效率86.6%,初步实验测得:响应时间(包括系统因素)130ns,量子效率大于10.1%,最小可探测光强3nJ.实验系统正在进一步改善,可以期望获得更好的实验值.Abstract: This paper introduces a new type Cs atomic resonance filter(ARF)detected by photoionization. The theoretical analysis gives the inherent time response of 10 ns,the linewidth of 62 MHz and quantum efficiency of 86.6%. In current experimental apparatus, the preliminary measurements give ARF’s time response of 130 ns,quantum efficiency greater than 10.1%and critical signal laser energy of 3 nJ.A better results will be obtained while the experimental apparatus improved.
