| Abstract: | With time evolution operator,it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of Gaussian line shape in a homogeneous broadening two level system.The oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level. |
