摘要
本文介绍了激光自旋投影噪声对铯原子磁强计灵敏度的影响，得出在原子蒸汽箱的优化条件下，即温度为105℃，体积为0.0785cm -3，分子密度为1.7×10 13 cm -3，激光自旋投影噪声的理论值约为1.23 ft·Hz -1/2。这些研究为Cs原子磁强计的实验研究提供了必要的基础。
Influence of Spin Projection Noise on the Sensitivity of Cs Atom Magnetometer
This article introduces the influence of laser's spin projection noise on the sensitivity of Cs atom magnetometer and concludes that the theoretical value of the spin projection noise is about1.23fT·Hz -1/2 under the optimization condi- tions of the atom steam chest, namely temperature as 105°C, volume as 0.0785cm 3 and molecular density as 1.7×10 13 cm -3 . Such research has provided us with the necessary basis for the experimental study on Cs atom magnetometer.
