摘　　要：在一级微扰理论近似下,研究了整形啁啾脉冲光场与二能级原子系统作用过程中的量子相干控制问题.利用惠更斯-菲涅耳原理解释了整形脉冲光场作用下量子态波函数的演化过程类似于时域"光栅衍射"效应;利用菲涅耳波带片方法研究了布居几率的增强效应.基于利用整形脉冲实现的量子相干控制和量子全息思想在理论上提出并论证了测量波函数的一种新方法.We study the interaction between the shaped chirped laser pulse and a two-level atomic system. The analytical solution of the population probability on the excited state is obtained by the first order perturbation theory. We show that the temporal evolution of the wave function on the excited state is similar to the grating diffraction. By varying the modulation adepth and the compensation phase we demonstrate that the quantum coherent control for the population probability on the excited state can be achieved. We present a new method for measuring the wave function by the quantum holography principle.
