摘要

基于线性啁啾高斯型脉冲串与V型原子系统的相互作用过程，探究了粒子布居的积累效应及相干布居转移的量子相干调控。在满足激光重复周期小于原子弛豫时间的条件下，选取适量的脉冲序列，即可实现粒子布居数在能级间的逐渐积累。采用高精度修正的四阶龙格-库塔法，对描述该相互作用的密度矩阵方程进行直接数值求解。研究结果表明，在脉冲串的光学参量保持不变的情况下，调整高斯脉冲串的啁啾因子或失谐量，会导致激发态上的粒子布居转移首次到达的峰值高度、振荡幅度及振荡次数均发生变化，同时粒子布居积累过程中的稠密宽度也随之变化。这一现象揭示了啁啾因子和失谐对量子干涉路径的调控作用，为相干布居的高效转移奠定了基础。

Abstract

Based on the interaction process between linearly chirped Gaussian pulse trains and V-type atomic systems

the accumulation effect of population and the quantum control of coherent population transfer were investigated. Under the condition that the laser repetition period is less than the atomic relaxation time

by selecting an appropriate number of pulse sequences

the gradual accumulation of population between energy levels can be achieved. The density matrix equation describing this interaction is directly numerically solved by using the high-precision modified fourth-order Runge-Kutta method. The research results show that when the optical parameters of the pulse train remain unchanged

adjusting the chirp factor or detuning of the Gaussian pulse train will cause changes in the peak height

oscillation amplitude and oscillation number of the first arrival of the population transfer on the excited state

and at the same time

the dense width during the population accumulation process will also change accordingly. This phenomenon reveals the regulatory effect of chirp factors and detuning on the quantum interference path

laying the foundation for the efficient transfer of coherent population.
