标题： Application of optical single-sideband laser in Raman atom interferometry

摘要： 基于频率倍频的I/Q调制器的光学单边带（OSSB）激光系统用于原子物理研究，特别是用于原子干涉测量，其中额外的边带会导致寄生跃迁。 OSSB技术的性能和二次谐波生成后的光谱进行了测量和分析。 额外的边带被抑制优于20 dB，并且显示寄生跃迁对不同空间位置处受激拉曼跃迁的影响被实验噪声以下。 该技术将促进具有更高精度和更少复杂性的紧凑型原子干涉测量传感器的发展。 显示英文摘要

摘要： A frequency doubled I/Q modulator based optical single-sideband (OSSB) laser system is demonstrated for atomic physics research, specifically for atom interferometry where the presence of additional sidebands causes parasitic transitions. The performance of the OSSB technique and the spectrum after second harmonic generation are measured and analyzed. The additional sidebands are removed with better than 20 dB suppression, and the influence of parasitic transitions upon stimulated Raman transitions at varying spatial positions is shown to be removed beneath experimental noise. This technique will facilitate the development of compact atom interferometry based sensors with improved accuracy and reduced complexity.
