Abstract :
The authors examine the influence of the light-shift effect on the frequency stability of a laser-pumped Rb gas cell standard for averaging time up to 104 s. The measured stability at the flicker floor is 7×10-14 for averaging times from 200 to 5000 s, providing that the laser frequency is properly set at the optical resonance frequency, and correcting for the variation of atmospheric pressure
