We present an optically pumped magnetometer working in a new operational mode-the light-shift dispersed Mz (LSD-Mz) mode. It is realized combining various features; (1) high power off-resonant optical pumping; (2) Mz configuration, where pumping light and magnetic field of interest are oriented parallel to each other; (3) use of small alkali metal vapor cells of identical properties in integrat...
With the demand for fast response of magnetic field measurement and development laser diode technology, self-oscillating laser-pumped atomic magnetometers have become a new trend. In this work, we designed portable VCSEL-pumped Cs atom magnetometer, including probe (optical path) circuits. The signal amplification feedback loop VCSEL control unit, cell temperature unit were realized. We tested ...
Although vector potentials are more intrinsic physical quantities than magnetic and electric fields, measuring them macroscopically is difficult. A double-nested Helmholtz-type potential coil, consisting of an elongated solenoid coil wound around a cylinder, producing uniform potential, was developed in this study. The carefully designed to reduce the influence leakage field scalar generated by...
Following the rapid progress in the development of optically pumped magnetometer (OPM) technology for the measurement of magnetic fields in the femtotesla range, a successful assembly of individual sensors into an array of nearly identical sensors is within reach. Here, 25 microfabricated OPMs with footprints of 1 cm(3) were assembled into a conformal array. The individual sensors were inserted...
