标题： Very large optical rotation generated by Rb vapor in a multi-pass cell

摘要： 顺磁法拉第旋转是一种用于原子传感的强大技术，广泛应用于量子非破坏性测量、基本对称性测试和其他精密测量中。 我们演示了多通光路细胞在法拉第旋转光谱中的应用，并观察到来自自旋极化的铷蒸气的偏振旋转超过100弧度。 与光学腔不同，多通细胞具有确定的光路次数，可用于测量大的光学旋转。 我们还观察到当铷原子处于对自旋交换碰撞免疫的相干叠加态时，横向自旋弛豫被抑制了10倍。 显示英文摘要

摘要： Paramagnetic Faraday rotation is a powerful technique for atom sensing widely used in quantum non-demolition measurements, fundamental symmetry tests, and other precision measurements. We demonstrate the use of a multi-pass optical cell for Faraday rotation spectroscopy and observe polarization rotation in excess of 100 radians from spin-polarized Rb vapor. Unlike optical cavities, multi-pass cells have a deterministic number of light passes and can be used to measure large optical rotations. We also observe a 10-fold suppression of transverse spin relaxation when Rb atoms are placed in a coherent superposition state immune to spin-exchange collisions.
