| Abstract: | The character of magnetic field state selected cesium beam tube and optically pumped one are contrasted in this paper.The principles of improving the signal-to-noise ratio of optically pumped cesium beam tube are presented and the experiments of LD-pumped cesium beam tube are reported here.The signal-to-noise ratio we acquired is 5750,this value is three times as much as the magnetic field state selected one's.This method will be very promising. |
