| Abstract: | The ladder three-level system including ground state, excited state and high excited state is investigated by using the density matrix equations. The coherence effect of ladder three-level system is analyzed, and absorption and dispersion curves of weak probe laser are obtained. The effects of interaction between high excited atoms and external electric field on the coherence effect are also investigated. The result shows that the interaction between high excited atoms or the external field can make the absorption curve and the dispersion curve shifted. |
