摘要:

我们提出了一种新的方法,使创建一个高对比度的暗共振在87 Rb蒸汽D2线。该方法是基于一个光学泵浦原子的工作状态的双频,线偏振激光辐射垂直于探测场传播。与传统的只考虑圆偏振探测光的方案相比,新方案的暗共振参数有了明显的改善,数值计算证实了新方案的定性考虑。

英文摘要:

We propose a novel method enabling to create a high-contrast dark resonance in the 87Rb vapor D2-line. The method is based on an optical pumping of atoms into the working states by a two-frequency, linearly-polarized laser radiation propagating perpendicularly to the probe field. This new scheme is compared to the traditional scheme involving the circularly-polarized probe beam only, and significant improvement of the dark resonance parameters is found. Qualitative considerations are confirmed by numerical calculations.
