  • 电光调制技术是产生拉曼光的几种方法之一, 其优点是系统简单、易搭建且环境适应性强. 然而, 这种调制技术会产生额外的边带光, 并影响冷原子干涉绝对重力仪的测量精度. 本文利用自行研制的可移动冷原子重力仪, 研究了边带效应对冷原子重力仪测量精度的影响. 详细分析了拉曼反射镜的位置、拉曼脉冲的作用时刻及其间隔、拉曼光的失谐等一系列参数与边带效应之间的关系, 实验发现这些参数对冷原子重力仪的精度评估有比较大的影响; 此外, 我们还发现在有边带效应的情况下, 原本不影响重力测量精度的实验参数也会影响最终的重力测量结果. 最后, 通过研究拉曼边带效应与拉曼光失谐之间的关系, 本文提出一种评估拉曼边带效应影响重力仪精度的方法. 本文结果为减小拉曼边带效应对冷原子重力仪测量精度的影响提供了依据.
    The technology of electro-optic modulation is one of the several methods of generating the Raman beams. The experimental system based on this method is simple and much easier to implement, and the environmental adaptability is strong as well. However, this kind of modulation technology will produce additional laser lines, which may affect the measurement accuracy of cold atom gravimeter. Based on a homemade transportable cold atom gravimeter, the influence of Raman sideband effect on the accuracy of cold atom gravimeter is investigated in this paper. We analyze in detail the relationship between Raman sideband effect and some experimental parameters, such as the height of Raman retro-reflection mirror, the time of free fall of the atoms, the detuning of Raman laser, etc. It is found that those parameters have a dominant influence on the measured gravity resulting from Raman sideband effect. Besides, it is also found that the gravity measurements will be sensitive again to some experimental parameters in the case of Raman sideband effect while these parameters are usually insensitive in case of laser system without sideband effect. Finally, we investigate the relationship between Raman sideband effect and Raman detuning, and presente a method of evaluating the gravity induced by Raman sideband effect. The experimental results in this paper can provide a reference for reducing the influence of Raman sideband effect on the accuracy evaluation of cold atomic gravimeter.
