标题： A superradiant laser based on two-photon Raman transition of caesium atoms

摘要： 我们提出了一种基于铯-133原子的双光子拉曼跃迁的超辐射激光，这些原子集体发射光子到一个低Q共振器的模式中，称为光学坏腔状态。 用于表征集体效应的自旋-自旋关联性得到了证明。 我们理论预测，这种光学辐射的线宽极窄，处于98(1)×10^-2 mHz范围内，由于集体效应，这一线宽小于跃迁本身，并且功率水平可达7(1)×10^-10 W，这可能为实现线宽为毫赫兹的光学钟提供了一种新的可能方法。 显示英文摘要

摘要： We propose a superradiant laser based on two-photon Raman transition of caesium-133 atoms which collectively emit photons on an ultra narrow transition into the mode of a low Q resonator known as optical bad-cavity regime. The spin-spin correlation which characterizes the collective effect is demonstrated. We theoretically predict that the optical radiation has an extremely narrow linewidth in the 98 (1) *10-2 mHz range, smaller than the transition itself due to collective effects, and a power level of 7 (1)*10-10 W is possible, which can provide a possible new way to realize an optical clock with a millihertz linewidth.
