Research on high sensitivity Mz rubidium laser optically pumped magnetometer

Abstract

The high sensitivity Mz rubidium laser optically pumped magnetometer has important applications in geomagnetic field measurement and geophysics exploration. In this paper we analyze the principle of Mz rubidium laser optically pumped magnetometer. We take rubidium 87 isotope ( 𝑅𝑏 ) as the core material of magnetometer, set up a high sensitivity laser optically pumped magnetometer experimental system and carry out magnetic measurement experiments. The experimental results show that the signal strength is 185 mV, the line width is 1.55 kHz. The intrinsic sensitivity of this magnetometer is 33.51 pT/Hz 1/2 . The research work provides technical support for the development of high sensitivity rubidium laser optically pumped magnetometer.
