Intensity correlation and anti-correlation in electromagnetically induced absorption

We present measurements of the intensity fluctuations of electromagnetically induced absorption (EIA) in the 5S₁/₂ (F = 2)-5P₃/₂(F' = 3) transition of ⁸⁷Rb atoms. Using a linearly polarized laser, the intensity fluctuations between two circularly polarized light components was generated by the...

Description
Summary:We present measurements of the intensity fluctuations of electromagnetically induced absorption (EIA) in the 5S₁/₂ (F = 2)-5P₃/₂(F' = 3) transition of ⁸⁷Rb atoms. Using a linearly polarized laser, the intensity fluctuations between two circularly polarized light components was generated by the spontaneously transferred atomic coherence of EIA medium. The intensity fluctuations due to spontaneous transfer of coherence were changed from correlation of EIA at on-resonance to anti-correlation of EIA at off-resonance. We also investigated the dependence of the values of second-order correlation function g(²)(0) at zero delay time on the temperature of the atomic vapor cell and the incident laser power.
