摘要
研究了原子与分子混合共振相互作用过程中准∧型四能级系统的量子干涉效应 ,特别对在驱动激光场作用下钠原子、钠分子和氩气组成的混合系统中出现量子干涉现象的机理作了分析 ,提出缀饰态能级有交叠区 ,并依据相应的理论计算 ,解释了原子光谱中的量子干涉增强效应。
The quantum interference effect of the quasi-∧-type four-level system, which is formed with the interaction between atoms and molecular, is investigated. The mechanism of quantum interference is analyzed which exists in the system of sodium atoms and argon gas incited by laser. The co-area existing in decoration-state is first presented and quantum interference enhancement in the area of atom spectrum is interpreted according to the computational result.
