| 摘 要： | 利用两束频率比为1:3的重合脉冲控制分子振转态布居转移. 计算结果表明, 初始态|0,0>到目标态|3,1>的跃迁概率接近100%. 两束脉冲的相位可以控制跃迁概率. 当φ 1 =1.68 π 时, 两束脉冲相互增强, 跃迁概率增加. 当φ 1 =0.64π 时, 两束脉冲相互抵消, 跃迁概率降低. 第二束脉冲的场强对布居转移过程具有较大影响.

| Abstract: | Rovibrational population transfer is controlled by a two-overlapping- pulse scheme in which the frequency ratio of the two pulses is 1:3.The calculated results show that nearly 100%of the population can be transferred from initial state |0,0〉to target state |3,1〉. The probability of population transfer can be controlled by pulse phase.Whenφ1=1.68π,the two pulses can be increased mutually and the probability of population transfer is also increased.Whenφ1=0.64π,the two pulses can be offset mutually and the probability of population transfer is reduced.The intensity of the second pulse has a significant effect on the population transfer. |
