Atomic magnetometer and operating method thereof |
| abstract |
Disclosed is an atomic magnetometer operating in a communication system using a magnetic signal of a very low frequency (VLF) band. An atomic magnetometer according to an embodiment of the present invention includes: a vapor cell including one or more alkali metal atoms; a pump light source providing a circularly polarized pump beam to the vapor cell; an irradiation light source providing a linearly polarized irradiation beam to the vapor cell; a magnetic signal detector for detecting a magnetic signal by measuring a polarization rotation angle from the linearly polarized irradiation beam passing through the vapor cell; and a bias magnetic field controller configured to control a bias magnetic field applied to the vapor cell. |
