德州大学奥斯汀分校 (UniversityofTexasatAustin)的实验小组最近以受激拉曼跃迁的方法将玻色 -爱因斯坦凝聚体 (Bose Einsteincondensate)中的铷原子转换为单一内部能态 ,温度约为 10 0nK的铷分子 (Rb2 ) [1] 。
2.
The results have shown that a stimulated Raman transition will be dominated, when some conditions are met by both the atom and the light field.
结果表明,当原子和光场由于多普勒效应满足一定条件时,将产生受激拉曼跃迁
2)  stimulated Raman transition
受激喇曼跃迁
3)  Raman transition
拉曼跃迁
1.

5)  Stimulated-Raman-adiabatic-passage
受激拉曼迁移过程
1.
It is possible to prepare atoms or molecules in a selected excited state, one efficient way is to transfer population by stimulated-Raman-adiabatic-passage, but we must understand off-resonant effects in coherent excitation in order to improve the efficient of transfer.
本文使用数值模拟的方法系统地分析了三能级系统在受激拉曼迁移过程中电子分布的转移情况,计算了系统处于双光子共振时和偏离共振时的转移率,分析了激光位移、偏离双光子共振、偏离单光子共振以及两束激光相对强度对转移率的影响。
6)  stimulated transition frequence
受激跃迁频率
补充资料:受激吸收跃迁概率
分子式:
CAS号:

性质:原子吸收能量为hv(h为普朗克常数)的入射光子,从基态跃迁到激发态。当在dt时间内,有dNoj个原子被激发,则dNoj与基态原子数目(No),辐射能量密度ρ(v),激发时间dt成正比,即dNoj=BojNoρ(v)dt。式中Boj为吸收跃迁系数。Boj与ρ(v)的乘积称受激吸收跃迁概率,定义为单位时间内光致吸收原子数与基态原子数的比值。
