详细分析了87Rb原子D1线形成的多能级EIT系统中,六能级(M+1型)系统简化为四能级Tripod系统的合理性,并通过理论计算进行了论证。计算表明,六能级系统和四能级Tripod系统中得到的结果几乎完全相同,也就是说,在我们的实验条件下,将该六能级系统简化为四能级Tripod系统是可行的。
The rationality of the simplicity from six level (Mq-1 type) system to four-level tripod system is detailedly analyzed and proved by the theoretical calculations in the multi-level EIT system of 87 Rb D1 line. The calculations show that the obtained results with the six-level system are almost same as that with the four-level tripod system. It means that under our experimental condition, the six-level system can be approximately simplified into the four-level tripod system.
