摘要

本文对紧凑型原子钟Ramsey-CPT共振中的光移进行了数值和解析研究。光移的数值计算基于Λ-type三态模型中的密度矩阵分析。通过分析得到了Raman-Ramsey格式下的光移估计方程。估计方程表达了光移与所有脉冲参数之间的关系。结果表明，估计方程与数值结果吻合较好。

Estimation of the light shift in Ramsey-coherent population trapping

We both numerically and analytically investigate on the light shift in Ramsey-CPT resonance for compact atomic clocks. The numerical calculation of the light shift is based on a density matrix analysis in Λ-type three state model. And the analytical method leads to an estimation equation of light shift in the Raman-Ramsey scheme. The estimation equation expresses the relationship between light shift and all pulse parameters. The results show that the estimation equation was reproduced well as the numerical results.
