This book contains all the information about a coherent control of the lateral shift or Goos-Hanchen shift. The coherent control of the Goos-Ha nchen shift has been investigated when a probe light is incident on a cavity which contains dispersive atomic medium. We consider different atom-field configurations for the intracavity atomic medium, i.e., electromagnetically induced transparency (EIT), Raman gain process and double Lamda (duplicated two-level). The sub- and super-luminal pulse propagation which correspond to normal and anomalous dispersion, respectively, through a dispersive atomic...
