Suppression method of AC-stark shift in SERF atomic magnetometer

Suppression method of AC-stark shift in SERF atomic magnetometer
Suppression method of AC-stark shift in SERF atomic magnetometer

In a spin-exchange-relaxation-free (SERF) atomic magnetometer with ultra-high sensitivity, the AC-Stark shift generated by circularly polarized light results in the attenuation of the SERF atomic magnetometer response, and the virtual magnetic field gradient induced by the AC-Stark shift can reduce the sensitivity of the SERF atomic magnetometer. In this paper, we use a hybrid optical pumping method to address the AC-Stark shift problem. By switching between left-hand and right-hand circularly polarized light and compensating the residual magnetic field of the magnetometer, the AC-stark shift could be reduced and then suppressed effectively.

Abstract

In a spin-exchange-relaxation-free (SERF) atomic magnetometer with ultra-high sensitivity, the AC-Stark shift generated by circularly polarized light results in the attenuation of the SERF atomic magnetometer response, and the virtual magnetic field gradient induced by the AC-Stark shift can reduce the sensitivity of the SERF atomic magnetometer. In this paper, we use a hybrid optical pumping method to address the AC-Stark shift problem. By switching between left-hand and right-hand circularly polarized light and compensating the residual magnetic field of the magnetometer, the AC-stark shift could be reduced and then suppressed effectively.
