摘要
微型化集成NV磁强计以其灵敏的磁探测性能以及优越的空间分辨率引起了广泛的研究,而NV磁强计所采用的高稳固体激光器体积过大发热严重,成为微型化集成NV磁强计投入实际应用的阻碍。开创性地提出将微型半导体激光元件与驱动器集成应用于NV磁强计测量调控系统实现微系统磁探测的系统优化,极大的推动了集成化磁强计的研发进程,并通过实验样机平台检测验证了微型化激光模组应用于金刚石NV色心测磁的可行性,实验结果表明在激光功率为5 mW,微波功率19 dBm的情况下,光子散粒噪声的极限灵敏度可以达到2.75nT√Hz,系统最小可检测磁场约为32 nT,验证了微型化系统的可行性与稳定性,为进一步微型化集成NV磁强计投入应用打下了基础。
The miniaturized integrated NV magnetometer has been widely researched for its sensitive magnetic detection performance and superior spatial resolution,but the high solid-state laser used in the NV magnetometer is too large in size and generates severe heat,which is an obstacle to the practical application of the miniaturized integrated NV magnetometer.This paper is a pioneer in proposing the integration of a miniature semiconductor laser component and driver into the measurement and control system of the NV magnetometer for system optimization of magnetic detection in microsystems,which greatly promotes the development of integrated magnetometers.This paper verifies the feasibility of the miniaturized laser module for diamond NV color core magnetometer through experimental prototype platform testing.The experimental results show that under the condition of laser power of 5 mW and microwave power of 19 dBm,the ultimate sensitivity of photon scattering noise can reach 2.75nT√Hz,and the minimum detectable magnetic field is about 32 nT,which verifies the feasibility and stability of the miniaturized system.The foundation was laid for further miniaturization and integration of the NV magnetometer into application.
