Negative Refractive Index in Atomic System Based on Incoherent Pump
An electromagnetically induced left-handedness scheme in atomic vapor medium is proposed. By applying an incoherent pump field to manipulate the populations in each level,the electric part and the magnetic part of the probe field are simultaneously amplified instead of strong absorption. It is shown that both the pumping rate of pump field and the intensity of the coupling field can affect the frequency band of negative refractive index of left-handed material (LHM).
