We introduce a novel and sensitive ns-resolved atomic magnetometer, which is at least three orders of magnitude faster than conventional magnetometers. We use the magnetic field dependence of the hyperfine beating of high-density spin-polarized H atoms, produced from the rapid photodissociation of HCl gas with sub-ns laser pulses and measured with a pick-up coil, to demonstrate ns-resolved magnetometry, and project sensitivity of a few nT for a spin-projection-limited sensor with 10 nl measurement volume after 1 ns measurement time. The magnetometer will allow ultrafast continuous B-field measurements in many fields, including spin chemistry, spin physics, and plasma physics.

纳秒分辨率原子氢磁强计

我们介绍了一种新颖且灵敏的 ns 分辨原子磁力计，它比传统磁力计快至少三个数量级。我们使用高密度自旋极化 H 原子的超精细跳动的磁场依赖性，由 HCl 气体与亚纳秒激光脉冲的快速光解产生并用拾音线圈测量，以证明纳秒分辨磁力测定法，并且在 1 ns 测量时间后具有 10 nl 测量体积的自旋投影受限传感器的投影灵敏度为几 nT。磁力计将允许在许多领域进行超快连续B场测量，包括自旋化学、自旋物理学和等离子体物理学。
