Abstract

Abstract Polarization of alkali vapor is a key parameter in the atomic magnetometer's response to the applied magnetic field. In this paper, estimating polarization is used by studying the transmission behavior of the pump beam as a function of intensity. In our study, the transmission of circularly polarized light exhibits nontrivial features such as nonlinear absorption and relaxation. The advantages of this method are its simplicity for characterizing polarization and its accuracy. The intensity and wavelength of the pumping laser are considered for studying polarization changes and polarization gradient. This method could apply directly to the quantum computing in devices like memory, gate, clock, and for reference cell. Also, this method is fast, reliable and accurate and doesn't need on resonance detection which makes it more suitable for ZULF NMR detection.
