论文摘要
我们提出了一种新型的原子干涉仪构型，该构型将大动量转移与增强光学谐振器的增强结合起来，目的是在水平方向上测量重力应变。使用Bragg衍射并利用谐振器提供的光学增益，我们在CM大小的谐振腰部中实现了$ 8 \ hbar k $的动量转移。重要的是，我们的实验使用了原始的谐振器设计，该设计允许大型谐振光束腰部，并消除了将原子捕获到空腔模式中的需求。我们通过测量谐振器的倾斜度变化在水平方向上证明了惯性灵敏度。该结果为将来的混合原子/光学引力波检测器铺平了道路。此外，我们方法的多功能性扩展到广泛的测量几何形状和原子源，为实现高度敏感的惯性原子传感器的实现开辟了新的途径。
We present a novel atom interferometer configuration that combines large momentum transfer with the enhancement of an optical resonator for the purpose of measuring gravitational strain in the horizontal directions. Using Bragg diffraction and taking advantage of the optical gain provided by the resonator, we achieve momentum transfer up to $8\hbar k$ with mW level optical power in a cm-sized resonating waist. Importantly, our experiment uses an original resonator design that allows for a large resonating beam waist and eliminates the need to trap atoms in cavity modes. We demonstrate inertial sensitivity in the horizontal direction by measuring the change in tilt of our resonator. This result paves the way for future hybrid atom/optical gravitational wave detectors. Furthermore, the versatility of our method extends to a wide range of measurement geometries and atomic sources, opening up new avenues for the realization of highly sensitive inertial atom sensors.
