鲁棒、高速、全光学原子磁力计

Robust, High-speed, All-Optical Atomic Magnetometer

J. M. Higbie, E. Corsini, D. Budker

摘要:

本文介绍了一种基于非线性磁光旋转效应的自振荡磁强计,它采用独立调制的泵浦光和未调制的探测光。该设备拥有超过$1\khz$的带宽。泵浦和探测均采用光纤传输,便于小型化和模块化。磁力计已与垂直腔面发射激光器(VCSEL),这是非常适合便携式应用,并与传统的边缘发射二极管激光器。对于$1\s$的测量时间,实现了大约$3 {\rm nG}$的灵敏度。

英文摘要:

A self-oscillating magnetometer based on the nonlinear magneto-optical rotation effect with separate modulated pump and unmodulated probe beams is demonstrated. This device possesses a bandwidth exceeding $1\khz$. Pump and probe are delivered by optical fiber, facilitating miniaturization and modularization. The magnetometer has been operated both with vertical-cavity surface-emitting lasers (VCSELs), which are well suited to portable applications, and with conventional edge-emitting diode lasers. A sensitivity of around $3 {\rm nG}$ is achieved for a measurement time of $1\s$.
