摘要:

我们在环境温度下操作的氮空位(NV-)金刚石磁强计,并研究其带宽的实验参数,包括光学和微波激发功率的依赖关系。我们介绍了一个分析理论,产生一个明确的公式的NV-自旋的合奏振荡磁场,如在NMR应用的响应。我们测得的探测带宽为1.6 MHz,灵敏度为4.6 nT/Hz^(1/2),这在具有这种有效体积的探测器中是前所未有的,并且接近我们实验的光子散粒噪声极限。

英文摘要:

We operate a nitrogen vacancy (NV-) diamond magnetometer at ambient temperatures and study the dependence of its bandwidth on experimental parameters including optical and microwave excitation powers. We introduce an analytical theory that yields an explicit formula for the response of an ensemble of NV- spins to an oscillating magnetic field, such as in NMR applications. We measure a detection bandwidth of 1.6 MHz and a sensitivity of 4.6 nT/Hz^(1/2), unprecedented in a detector with this active volume and close to the photon shot noise limit of our experiment.
