| Abstract: | The physical mechanism and producing processes of quantum beats on population relaxation for V level atoms in vacuum by using time delayed four wave mixing(TDFWM) was theoretically studied in this paper.On the basic review of both coupling between vacuum and atoms and interaction between broad bandwidth light pulses and atoms,the behavior of output signal intensity was analyzed and discussed. |

| Keywords: | Degenerated four wave mixing V level atom Vacuum coupling Population relaxation Quantum beats |
