摘　　要：通过对比磁选态和光抽运铯束管的不同特性,阐述了光抽运方式能够提高信噪比的原理。介绍了用稳频半导体激光抽运的铯束管的实验装置和结果。实验得到的信噪比为5750,该值是磁选态方式的3倍多,表明这种方法很有发展前景。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.
