摘要
针对四能级理论模型的第二种极限情况 ,提出了 Ba- Sr激光感生碰撞能量转移系统 ,该系统满足 |ω2 1| |ω4 3|。利用四能级理论模型对该 Ba- Sr系统进行了数值计算 ,并与三能级近似理论模型的计算结果进行了比较。通过比较四能级理论与三能级近似理论模型的计算结果 ,进一步证实了当 |ω2 1| |ω4 3|时 。
The laser induced collisional energy treasfer (LICET) is Ba Sr system in suggested, which satisfies the condition ｜ω 21 ｜｜ω 43 ｜. And the results of numerical calculations of the Ba Sr system are obtained from the four level model and the conventional three level model respectively. The results of numerical calculations in Ba Sr further prove the theoretical prediction that the four level model can be simplified as a conventional three level model if the condition ｜ω 21 ｜｜ω 43 ｜ is satisfied.
