【摘要】 用扫描式Fabry-Perot平涉仪测量了经内充缓冲气体的Rb⁸⁵滤光泡滤光后的Rb⁸⁷D₁线谱线轮廓,考察了不同的缓冲气体种类和压力、滤光泡长度及Rb⁸⁷谱灯光强对滤光效果的影响,指出在Rb⁸⁵滤光泡内充以适当的混合气体,可以增强滤光效果,从而提高光抽运汽泡型Rb频标性能。更多还原

【Abstract】 The spectral profiles of Rb⁸⁷D₁ line, filtered by the cell containing Rb⁸⁵ atoms and various buffer gases under various pressures, were observed by means of a scanning Fabry-Perot interferometer. The influences of the kind and the pressure of the buffer gas, the length of filter cell and the intensity of lamp light on filtering effect were examined. The cell containing appropriate amount of mixed kryton-argon gases shows a desirable filtering effect and may be used to improve the performance of the rubidium frequency standard pumped by the filtered pumping light.更多还原
