Abstract
The linear and non-linear optical properties of three-level systems get a great importance from both theoretical and experimental points of view. This is due to the phenomena related to these systems, like electromagnetic induced transparency (EIT), coherent population trapping (CPT) and coherent adiabatic population (CAP). In contrast to CPT which is a‘‘spectroscopic’’ phenomenon that involves only modifications to the material states in an optically thin sample.
