一、引言在研制铷87脉泽的过程中,就已经予料其特点是短期稳定度非常好。这种估计的主要根据是:其输出功率比较高,而且带宽窄。虽然对连续波或脉冲工作状态脉泽工作所依据的基本理论进行过大量的研究,但确定其实际稳定度的工作搞的不多。测量这种稳定振荡器频率稳定度的简单方法,是用两个这种振荡器产生差拍讯号,并对合成讯号进行统计分析。为此,制成囚禁原子用的两个“石英腔体—石英泡”型铷87脉泽。这种型式的比真空密封不锈钢腔体型式的长期、中期频率
I. INTRODUCTION In the process of developing rubidium 87 maze, it has been expected that its short-term stability is very good. The main basis for this estimate is: its output power is relatively high, and the bandwidth is narrow. Although a great deal of research has been conducted on the basic theories on which masers work in continuous wave or pulsed mode, the work of determining their actual stability is limited. A simple way to measure the frequency stability of a stable oscillator is to generate a beat signal with two such oscillators and perform a statistical analysis of the resultant signal. For this purpose, two “quartz cavity-quartz bubble” Rubidium 87 masers were made for trapped atoms. This type of vacuum-tight stainless steel cavity type long-term, medium-term frequency
