论文摘要
监测和稳定激光对的功率比对高精度原子干涉仪至关重要，尤其是随着紧凑型电气调制的全纤维激光系统的盛行。在这封信中，我们演示了一种新的方法，可在原位探测激光对的相对功率，并使用高分散量实际成像的分阶段阵列（VIPA）Etalon稳定两个拉曼激光器的功率比。在原子干涉仪序列探测激光功率转化方面的次微秒分辨率达到了，尽管环境障碍有环境障碍，但两个拉曼激光器（PRTR）的功率比以高带宽紧密锁定，显示了艾伦偏差为$ 4.39 \ $ 4.39 \ times 10^{-5} $ 1000 s $ s时。该方法提供了一种稳定PRTR并诊断多频激光系统的新方法，用于原子干涉仪，并可以在广泛的量子传感情景中找到潜在的应用。
Monitoring and stabilizing the power ratio of laser pairs is significant to high-precision atom interferometers, especially as the compact electro-optic modulated all-fiber laser system prevails. In this Letter, we demonstrate a novel method to in-situ probe the relative power of laser pairs and to stabilize the power ratio of two Raman lasers using a high-dispersion virtually imaged phased array (VIPA) etalon. Sub-microsecond resolution on probing laser power transformation during atom interferometer sequence is achieved and the power ratio of two Raman lasers (PRTR) is tightly locked with high bandwidth despite of environmental disturbances, showing an Allan deviation of $4.39\times 10^{-5}$ at 1000 s averaging time. This method provides a novel way to stabilize the PRTR and diagnose the multi-frequency laser systems for atom interferometers and could find potential application in broad quantum sensing scenarios.
