弱场中光抽运极化Eu原子束的制备

The producing of Eu polarized atomic beam by means of optical pumping in the weak field

自五十年代首次实现光抽运技术以来 ,人们用它已对多种原子进行了极化原子束制备的研究[1～ 5] ,但所有这些工作只是以相对简单的碱金属原子为对象 ,而对价电子数大于 1的复杂原子的极化原子束的制备目前尚未见报道。描述了用一台连续波染料激光器对复杂原子Eu进行了弱场制备极化原子束的实验研究 。

The polarized atomic beam of many kinds atoms had been researched, since the laser pumping technique was put forward by Mr.Kastler. But all those work based on the relatively simple Alkaline metal atoms. The same work on the complex atom which has more than one valence electrons has not been reported until now. In this paper, we described the experiment of producing Eu polarized atomic beam pumped by only one coherent Dye Laser in the weak field. And some satisfied results have been achieved.
