We have theoretically investigated the population transfer and the selective excitation of vibrational states of the target state in a three-state Na 2 molecule using the chirped adiabatic passage. The population transfer among electronic states is studied. Compared with the single negative chirped pulse, complete population transfer can be achieved by using a positive chirped pulse. The effects of laser parameters on vibrational population distribution are discussed, and the selective excitation of vibrational states can be achieved by adjusting the central frequency. Finally, we give the method of selective excitation of specific vibrational states.

chi激光脉冲选择性激发三态Na 2分子的振动态

我们已经从理论上研究了using的绝热通道在三态Na 2分子中目标态的振动态的种群转移和选择性激发。研究了电子州之间的人口转移。与单个负negative脉冲相比，使用正chi脉冲可以实现完整的种群转移。讨论了激光参数对振动种群分布的影响，并且可以通过调节中心频率来实现振动状态的选择性激发。最后，我们给出了选择性激发特定振动状态的方法。
