摘要
提出了基于磁不敏态的Raman-Nath对称分束方法和内态干涉方案。基于磁不敏态的干涉对磁场涨落敏感性较低,有助于增强干涉条纹的对比度。如果将Raman-Nath对称分束方法应用于路径共轭的原子陀螺仪,系统噪声可显著降低。通过优化双脉冲对称分束参数,可以获得较高的衍射效率。内态干涉方案成功解决了干涉动量态易受环境影响的问题。
Abstract
The method of Raman-Nath symmetric beam splitting based on magnetically insensitive states and the scheme of internal state interference are proposed. The interference based on magnetically insensitive states is insensitive to the magnetic fluctuation, which is beneficial to the contrast enhancement of interference fringes. If such a Raman-Nath symmetric beam splitting method is applied in the path-conjugate atom gyroscope, the system noise is obviously reduced. By means of optimizing the symmetric-beam-splitting parameters of double pulses, it is possible to obtain a high diffraction efficiency. The scheme of internal state interference is successfully used to solve the problem of momentum state interference being susceptible to the environment.
