| 摘 要： | 本文主要研究锶原子光钟Doppler冷却过程中再抽运光对俘获冷原子参数的影响,实验上测得再抽运光光强和失谐跟所俘获原子数目的关系,并且测得了在同时注入再抽运光707 nm和679 nm后使俘获冷原子的数目提高了17倍,分析了再抽运光的失谐对俘获原子数目的影响,测得了再抽运光707 nm在失谐5 MHz的情况下俘获原子数目的波动小于3‰.

| Abstract: | We have conducted experimental investigations on the effect of repumping laser on the cooling and trapping of strontium atoms. More than 3.1×10888Sr atoms have been trapped with 679 nm and 707 nm repumping laser added. The two repumping lasers enhance the trappopulation by a factor of 17. We also made experimental investigations on the effect of 707 nm repumping laser detuning on the cooling and trapping of strontium atoms. The fluctuation of atom trapping population is less than 3 ‰ when the detuning from 707 nm is 5 MHz. |
