摘要

The atomic spin co-magnetometer operating in the spin-exchange relaxation-free regime is a promising rotation sensor for its ultrahigh sensitivity to inertial forces. However, it was found that the bias magnetic sensitivity (BMS) of the comagnetometer was much larger than theoretically expected, making magnetic noise a dominant error. This paper reports on the experimental results of the effect of cell temperature on the BMS. It is found that the BMS increases rapidly as the cell temperature rises. This is attributed to the polarization gradient of atomic spins induced by the absorption of the pump beam by the atoms. The experiments and theory reveal that a high-power laser source for pumping is essential for the suppression of BMS and the improvement of bandwidth in the co-magnetometer.
