The most important parameter inversion lifetime of the laser transition gas studied and described. The inversion lifetime of 2P3/2  2D5/2 and 2P1/2  2D3/2 transitions of the copper atom are obtained as a function of the electron temperature. It is also studied that the population inversion decays as time passes and ultimately it becomes zero. The amplification of the radiation in the laser medium takes place as long as population inversion is present in the medium. The inversion lifetime of the transition is obtained under two conditions as the exciting pulse width narrower than the laser pulse width and exciting pulse width narrower comparable the laser pulse width. The effect of initial inversion density on the inversion lifetime is also investigated.
