Superradiant active clocks operating on narrow linewidth clock transitions are predicted to achieve precision orders of magnitude higher than any currently existing optical atomic clocks. We introduce a theory of superradiant lasing and implement it for the example of 40Ca atoms. The presented model, however, is valid for any two- or three-level system in an optical lattice. We perform a feasibility analysis and suggest a set of parameters for the experimental fulfillment of superradiant lasing in Ca. Moreover, we present an overview of different magic wavelengths for the 4s2 1S0 ↔ 4s4p 3P1 (mJ = 0) transition in Ca for different polarizations and a robustness analysis of these magic conditions. We also report the magic-zero wavelengths for the 4s4p 3P1, mJ = 0 state.

40 Ca原子超辐射激光的表征及可行性研究

预计在窄线宽时钟跃迁上运行的超辐射有源时钟将实现比目前任何现有的光学原子钟更高的精度。我们介绍了一种超辐射激射理论,并以40 Ca原子为例进行实现。但是,提出的模型对光学晶格中的任何两级或三级系统均有效。我们进行了可行性分析,并提出了一组用于实现Ca中超辐射激光实验的参数。此外,我们提出了不同魔波长为4的概述小号2 1小号0 ↔4小号4 p 3 P 1Ĵ= 0)不同极化的Ca跃迁以及这些魔术条件的鲁棒性分析。我们还报告了4 s 4 p 3 P 1m J = 0状态的魔术零波长。
