摘要
在原子与光相互作用的过程中,磁场调控为量子精密测量中操纵原子能级和相互作用提供了一种有价值的方法.在高精密量子传感实验中,实现精确测量离不开磁场系统和光学探测系统之间的合作.为了满足不同光学探测系统的磁场需求,制作了一套可快速切换的磁场系统和交变磁场系统,并将此装置与Lee-Whiting线圈结合实现了kHz的交变磁场信号.在实验中,可以通过调节电感和电容元件的大小实现交变磁场的频率调节,以及增加元件的可调节范围扩大交变磁场的频谱.实验结果证明了这种方法在产生交变磁场方面的可行性,可用于交变磁场下冷原子吸收光谱的研究.
Abstract
Magnetic field control provides a valuable method for manipulating atomic energy levels and interactions in quantum precision measurements during the interaction between atoms and light.In high-precision quantum sensing experiments,precise measurement cannot be achieved without the cooperation between magnetic field systems and optical detection systems.In order to meet the magnetic field requirements of different optical detection systems,a set of fast switching magnetic field systems and alternating magnetic field systems were developed,and this device was combined with Lee-Whiting coils to achieve kHz alternating magnetic field signals.In the experiment,the frequency adjustment of the alternating magnetic field can be achieved by adjusting the size of the inductance and capacitance components,as well as increasing the adjustable range of the components to expand the frequency spectrum of the alternating magnetic field.The experimental results have demonstrated the feasibility of this method in generating alternating magnetic fields,which can be used for the study of cold atomic absorption spectroscopy under alternating magnetic fields.
