DOI: 10.1103/physrevapplied.22.034033

Abstract: This paper describes the light-shift laser-lock (LSLL) technique, an alternative method intended for laser-based compact atomic clocks. The technique greatly simplifies the laser setup by stabilizing the pumping-laser frequency to the same atoms involved in… read more here.

DOI: 10.1109/jsen.2018.2877771

Abstract: The light shift is an important error source for atomic magnetometers. It would vanish if the frequency of the circularly polarized light is tuned to the optical resonance center. For high-density alkali-metal atomic magnetometers, the… read more here.

DOI: 10.1109/jsen.2024.3521412

Abstract: A light shift in a spin-exchange relaxation-free (SERF) atomic magnetometer (AM) generated by detuning of circularly polarized pump light results in deviations of orthogonality measurement and attenuation of magnetometer response. In this article, we propose… read more here.

DOI: 10.1364/oe.456937

Abstract: The transverse light-shift can induce non-negligible polarization error in the output signal of spin-exchange relaxation-free (SERF) co-magnetometer. In this paper, a novel method for rapid measurement of transverse light-shift based on the error of steady-state… read more here.
