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 recorded quantum-enhanced measurements of the Rb 5 hyperfine structure with reduced requirements for the Raman pump laser power and Rb vapor number density.
我们研究了利用在铷蒸汽中产生的双模强度压缩孪生光束，通过双光子拉曼跃迁来提高光谱测量灵敏度的前景。作为原理验证演示，我们记录了对铷5超精细结构的量子增强测量，同时降低了对拉曼泵浦激光功率和铷蒸汽数密度的要求。
