Strong Coherent Light Amplification with Double Electromagnetically Induced Transparency Coherences

Abstract We experimentally demonstrate coherent amplification of probe field in a tripod-type atoms driven by strong coupling, signal and weak probe fields. We suppress linear and nonlinear atomic absorptions for resonant and near resonant probe via double electromagnetically induced transparency (D...
