Abstract

The variation in the <sup>87</sup>Rb <i>D</i><sub>1</sub> (λ = 794.8 nm) pumping light profiles due to <sup>85</sup>Rb filter cell temperatures (< 80°C) has been explained by considering both the shift and broadening of the <sup>85</sup> Rb absorption spectrum caused by low-pressure foreign gases (< 200 Torr). The coefficients of the pressure shift and broadening by N<sub>2</sub> gas were obtained as -8.0 ± 0.5 and 11 ± 1 MHz/Torr, respectively. The intensity ratio and difference of two peaks in the profiles were calculated in order to discuss the variation in the profiles quantitatively. The foreign gas He was examined for comparison. The absorption coefficient of Rb was also discussed.
