Observation of electromagnetically induced absorption in a vee + ladder system

Abstract

We experimentally demonstrate electromagnetically induced absorption (EIA) in a vee + ladder system. The experiment is done using the low-lying energy levels of ${}^{87}$Rb. A theoretical model of the system is made that reproduces the experimental results. We study the dependence of the characteristics of the EIA resonance on various combinations of the different control powers. We also explore the contribution of various incoherent phenomena that affect the EIA signal.
