利用基频与倍频脉冲控制扩展“ladder”式跃迁∗
The extended “ladder” transition controlled by two harmonic pulses
摘要
Abstract
The extended “ladder” transition controlled by two harmonic pulses is investigated by using a time-dependent quantum wave packet method. The molecular population transfers from the state |0, 0⟩ to the states |5, 0⟩ and |5, 2⟩induced by the fundamental and second-harmonic pulses, and to the states|5, 3⟩and|6, 2⟩induced by the fundamental and third-harmonic pulses. The calculated results show that the two harmonic pulses can induce a nearly 100% of population to transfer to the target state. The relative phase of two pulses can affect the population distribution. The variation of population has a period of π for the fundamental and second-harmonic pulses, and a period of 2π for the fundamental and third-harmonic pulses.关键词
