摘要

Rb光谱灯是Rb原子频标的重要部件。 Rb光谱灯发出的光含有两种成分, 一种是对原子跃迁信号有贡献的有效光成分, 一种是仅体现为光噪声的无效光成分。 尽可能地增强Rb光谱灯有效光成分并抑制无效光成分, 对于提高Rb原子频标锁频环路的信噪比从而改善Rb原子频标的频率稳定度具有重要意义。 利用单色仪获得了分别充有起辉气体Ar, Kr和Xe的三种常用Rb光谱灯的光谱, 分析了三种Rb光谱灯的光谱特性, 讨论了如何提高有效光强和抑制无效光强的问题。 实验和分析结果表明, Rb光谱灯有效光强与所用起辉气体的种类和灯泡的工作温度密切相关。 灯泡工作温度较低时, Xe灯有用光强最大, Kr灯次之, Ar灯最低; 当灯泡工作温度较高时, Xe灯有用光强仍最大, Ar灯次之, Kr灯最低。 分析还表明, 采用合适的光学滤光方法可以有效地滤除Rb光谱灯的无效光成分。

Abstract

Rubidium spectral lamp is one of the critical parts in a rubidium atomic frequency standard (RAFS). The light emitted from the spectral lamp contains two components, one is the useful component, which contributes to the atomic transition signal, and the other is the useless component, which acts only as the light noise. In order to improve the signal-to-noise ratio of the frequency locking loop of a RAFS, and therefore to obtain a highly stable RAFS, it’s very important to enhance the useful light component and suppress the useless component. In the present work the light spectra of the three commonly used rubidium spectrum lamps with bulbs separately filled with buffer gases argon, krypton and xenon were obtained by means of a monochromator. The spectra were analyzed and the methods to enhance useful light intensity and reduce useless light intensity were discussed. Results showed that the useful light intensity strongly depends on the types of buffer gases and the bulb temperature. In the whole range of bulb temperature, the Xe lamp had the highest useful light intensity among the three lamps. The Kr lamp showed a higher useful light intensity than the Ar lamp at low bulb temperature, while at high bulb temperature the Ar lamp showed a higher useful light intensity than the Kr lamp. Analysis also indicates that the light noise of a rubidium spectrum lamp can be effectively minimized by adopting suitable light filtering technique.
