Obtaining high refractive index with vanishing absorption via spontaneously generated coherence and incoherent pumping
چکیده انگلیسی

A three-level ∧∧-model atomic system with incoherent pumping is proposed to achieve high refractive index without absorption. In this kind of model, two lower levels are near-degenerate levels. It is found that high refractive index accompanied by vanishing absorption can be always accomplished by adjusting some related parameters. Although probe field is very weak, the SGC effect is prominent in the presence of incoherent pumping.
