基于Rb原子电磁诱导透明的量子干涉实验研究
Quantum interference effects studied experimentally in the D2 line of 85Rb vapour
摘要
报道了基于85RbD2线电磁诱导透明(EIT)的量子干涉现象,发现当一耦合光和探测光之间满足拉曼共振条件时出现电磁诱导透明现象,在某些条件下也观察到电磁诱导吸收(EIA).而当用一束耦合光和一束泵浦光共同作用于5S1/2,F=3→5P3/2,F′=3和5S1/2,F=3→5P3/2,F′=4能级上时,探测光的吸收谱表现出三峰结构,并且峰强弱与两耦合光之间的相对强度有关.
Abstract
The paper report an experimental observation of the electromagnetically induced transparency (EIT) in the D 2 line of 85 Rb atoms. When a coupling laser for 5S 1/2 ,F=3→5P 3/2 ,F′ is Raman resonant to the probe laser in 5S 1/2 ,F=2→5P 3/2 ,F′ , EIT peaks apparently appear. Under certain conditions, absorption enhancement due to the electromagnetically induced absorption (EIA) was also recorded together with the EIT. A lambda coupling scheme with two strong lasers (a coupling laser and a pumping laser) was realized, the spectrum of the probe laser exhibits more complex structure, revealing rich quantum coherence interactions.
