摘要
介绍一种新的小型铷频标腔泡系统的结构特点和频移特性。研究了腔牵引效应、微波功率频移、光频移和缓冲气体温度系数对铷频标输出频率的影响。结果表明,上述因素影响都在可以接受的范围内。此腔泡系统体积小、信噪比高、参数优化方便。利用此腔泡系统可以制成小型化、高性能的铷原子频标。
The structure and frequency shift characteristics of a new kind of miniature cavity-cell assembly for rubidium atomic frequency standards (RAFS) are reported. The cavity pull effect, microwave power shift, light shift and temperature coefficient which mostly influence the performance of RAFS are studied. The results indicate that the influences are controlled in an acceptable range. The cavity-cell assembly is of small size and high signal to noise ratio. The parameters of the assembly could be conveniently optimized. This cavity-cell assembly can be used to make a miniaturized rubidium atomic frequency standard with high performance.
