论文摘要
我们介绍了对基于布拉格的轻脉冲原子干涉仪中原子光学操纵不完善的影响的详细研究。抗谐振的高阶衍射会导致种群损失，虚假干涉仪路径和衍射阶段。在路径依赖性形式主义中，我们在数值上研究了各种效果，并分析了由外相或重力引起的干扰信号。我们比较了逆转录设置中的一阶单阶单阶和双bragg衍射。在双重布拉格衍射中，相位瑕疵导致由于三路的干扰而导致殴打。通过添加双衍射的外出出口端口的种群，可以避免衍射阶段的某些影响。
We present a detailed study of the effects of imperfect atom-optical manipulation in Bragg-based light-pulse atom interferometers. Off-resonant higher-order diffraction leads to population loss, spurious interferometer paths, and diffraction phases. In a path-dependent formalism, we study numerically various effects and analyze the interference signal caused by an external phase or gravity. We compare first-order single and double Bragg diffraction in retroreflective setups. In double Bragg diffraction, phase imperfections lead to a beating due to three-path interference. Some effects of diffraction phases can be avoided by adding the population of the outer exit ports of double diffraction.
