摘要
通过求解含时Ｓｃｈｒｏｄｉｎｓｅｒ方程，对于原子在激光场的共振和非共振驱动下向各个态的跃迁几率进行了计算和分析，探讨了跃迁几率的时间特性以及随激光参数的变化规律，揭示了光场与原子系统相互作用的相干性和选择性。计算并验证由解析解所预测的激发态粒子数布居的峰值和实现粒子数反转所应满足的条件。
The results of both analytic and numerical treatments of the four - level Schrodinger equation are displayed. Transition Probabilities to various states for the cases of on-resonance and off-resonance are calculated. Dependences of probability on time and on characteristics of laser fields are investigated. Selectivity and coherence of the interaction between monochromatic laser fields and isotopic atomis are examined. The conditions under which the population inversion tukes place derived from the analytic solutions are confirmed.
