Via hyperfine spectral profile measurements, the spectrum characteristics and isotope filtering effect of the rubidium spectrum lamp were studied under the circumstance that both the lamp bulb and the filtering cell are filled with argon buffer gas. Spectral profile distortion of the 87Rb-Ar spectrum lamp was observed, and it was found that a lower temperature in the lamp bulb could minimize the distortion. The results also showed that the pressure, length and operation temperature of the filtering cell have evident influences on the filtering effect. After design and operation parameters being optimized, the spectrum lamp and the filtering cell were used in a rubidium frequency standard, and the short-term frequency stability was greatly improved.
