| 摘 要： | 在假设输入光场为单模相干场,原子制备在最高激发态的条件下,运用全量子论方案研究了Kerr介质中一个级联三能级原子布居随时间演化特点。结果表明:当单光子失谐量较大时,改变输入光场强度可以实现原子跃迁转移。文中对该现象给出了一种解释。

| Abstract: | Under the assumption that the input field is in a coherent state and the atom is prepared in the most excited state,the time evolution of atomic populations of a cascade atom embedded in a Kerr medium is investigated by using the full quantum mechanical scheme.It is found that,with a large single-photon detuning,an atomic transition transfer can be realized by changing the intensity of the input field.An explanation to the phenomena is proposed. |
