摘要:

原子系综基态内的布居分布在各种量子光学过程中具有重要意义。我们提出了一种方法来重建详细的人口分布从一组吸收测量与各种频率和偏振,通过利用探测跃迁的偶极矩阵元素之间的差异。该技术是实验上实现的热铷蒸气,展示了人口为基础的分析,在两个光泵浦的例子。结果被用来验证和校准一个详细的数值模型,并讨论了重建方案的局限性,这是由于偶极矩阵元素的对称性。

英文摘要:

The population distribution within the ground-state of an atomic ensemble is of large significance in a variety of quantum optics processes. We present a method to reconstruct the detailed population distribution from a set of absorption measurements with various frequencies and polarizations, by utilizing the differences between the dipole matrix elements of the probed transitions. The technique is experimentally implemented on a thermal rubidium vapor, demonstrating a population-based analysis in two optical pumping examples. The results are used to verify and calibrate an elaborated numerical model, and the limitations of the reconstruction scheme which result from the symmetry properties of the dipole matrix elements are discussed.
