调谐耦合场作用下的电磁诱导透明和增益
Electromagnetically Induced Transparency and Gain under The Effect of Tuned Coupling Field
摘要
Abstract
Electromagnetically induced transparency (EIT) with extremely narrow spectral width is obtained in a well-studied lambda three level system where a coupling field and a probing field interact with two optical transitions. By tuning coupling field, it excites the transitions between two ground state hyperfine levels and excited state level. In this paper, both EIT and spontaneous radiation induced coherent dip can be obtained,and even the gain is observed to superpose to the EIT window. By discussing the behaviors of probing field absorption profiles under the effect of the tuned coupling field, it can be seen that there are quantum interference and coherence between EIT and spontaneous radiation induced coherent dip, and the coherence becomes remarkable when the excitation frequency of the coupling field satisfies certain conditions.关键词
