论文摘要
我们研究了使用RB蒸气产生的两种模式强度挤压双束的前景，以通过参与两光子拉曼转变来提高光谱测量的灵敏度。作为原理演示的证明，我们证明了RB $ 5D_ {3/2} $超细结构的量子增强测量值，对拉曼泵激光功率和RB蒸气数密度的需求降低。
We investigate the prospects of using two-mode intensity squeezed twin-beams, generated in Rb vapor, to improve the sensitivity of spectroscopic measurements by engaging two-photon Raman transitions. As a proof of principle demonstration, we demonstrated the quantum-enhanced measurements of the Rb $5D_{3/2}$ hyperfine structure with reduced requirements for the Raman pump laser power and Rb vapor number density.
