锶原子Doppler冷却中再抽运光对原子俘获影响的理论和实验研究
The theoretical and experimental investigation of repumping laser impact on cooling and trapping of strontium atoms
摘要
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.关键词
