In this paper we report the measurement of the frequency Stark shift of the ground-state hyperfine transition of 133Cs observed in a vapor cell through a Λ excitation scheme.

Abstract

In this paper we report the measurement of the frequency Stark shift of the ground-state hyperfine transition of 133Cs observed in a vapor cell through a Λ excitation scheme. The measured value of the quadratic Stark coefficient is k=(−2.05±0.04)×10−10 Hz∕(V∕m)2 when the electric field is perpendicular to the quantization axis. A comparison with the values previously reported in literature is given in view of its interest for the evaluation of the blackbody radiation shift in the primary frequency standards.
