摘　　要：由于金刚石氮空位(NV)色心的磁测量装置兼具高空间分辨率与高测量灵敏度的优点可用于半实物仿真暗室内弱磁场的测量。对金刚石NV色心磁测量装置的圆极化操控技术进行研究,设计圆极化谐振器,并结合高输出功率的射频放大器实现NV色心能级的选择性操控。通过光学检测磁共振(ODMR)与拉比振荡实验验证操控系统的性能,结果表明该系统的圆极化度高达93.24%,可实现高效的圆极化量子态操控。该技术有望在磁测量中去除线圈或永磁体提供的磁场偏置,缩小NV色心磁测量装置的体积,对暗室内弱磁场测量技术的发展具有重要意义。Due to the advantages of high spatial resolution and high measurement sensitivity,the magnetic measurement device based on diamond nitrogen vacancy(NV)center can be used for the measurement of weak magnetic field in the darkroom of hardware-in-the-loop simulation.The circular polarization manipulation technology of the magnetic measurement device based on diamond NV center was studied.The circular polarization resonator was designed,and the selective manipulation of the NV center energy level was realized by combined with a high output power radio frequency amplifier.The performance of the manipulation system was verified by optical detection magnetic resonance(ODMR)experiment and Rabi oscillation experiment.The results show that the circular polarization of the system is as high as 93.24%,which can achieve efficient circular polarization quantum state manipulation.The technology is expected to remove the magnetic field bias provided by coils or permanent magnets in magnetic measurement,and reduce the volume of magnetic measurement device based on NV center,which is of great significance for the development of weak magnetic field measurement technology in the darkroom.
