Abstract

We investigate the effects of spontaneously generated coherence (SGC) on the electromagnetically induced transparency features in a four-level Lambda-type system. We show that double-transparency windows and a controllable narrow absorption peak can be obtained with the presence of SGC. We present an equivalent system without the rigorous requirement of close-lying levels to observe the phenomena. We also experimentally demonstrate the corresponding features in a rubidium atomic beam.

摘要

我们研究了自发产生的相干性（SGC）对四能级Λ型系统中电磁诱导透明特性的影响。我们表明，在存在SGC的情况下可以获得双透明窗口和一个可控的窄吸收峰。我们提出了一个等效系统，该系统对能级相近没有严格要求就能观察到这些现象。我们还在铷原子束中通过实验证明了相应的特性。
