摘要
本文用数值计算研究了强激发二能级原子双光子过程粒子数反转的崩塌与复苏性质和光子统计演化,结果发现,至于崩塌与复苏的性质与低激发情况不同,将随着工值的不断增大,场与原子的非线性耦合越来越强,重复地出现复苏收缩现象.
In this paper,the collapse and revival properties of atomic particle rfumber inversion and thestatistical evolution of the mean photon number in the two-photon process under strong excitation ofcoherent field are studied by numerical calculation- The results show that the nonlinear coupling of thefield with the atom is getting the stronger and the stronger,and the phenomenon of revival shrink willarise repeatedly,as the values of n beeome greater gradually.
