  4. We study the time evolution law of the atomic response in an open - type inversionless lasing system when the probe or driving field is off - resonance, and compare the law with that obtained when the probe and driving fields are resonant. we find that the detuning has considerable effects on the time evolution law : when the probe or driving fields is off - resonance, the dispersive responses for the probe and driving fields are no longer 0 and the two - photon coherence is no longer a pure real ; the variation of the probe detuning can make the time evolution law of the population distributions and the gain ( absorbtion ) of the driving field changing obviously ; with detuning increasing, the time evolution behavior of the gain ( absorbtion ), dispersion of the probe field and the two - photon coherence will gradually diviate from the evolution law of the standard damped oscillator ; with the driving detuning increasing, the oscillating time of the dispersion of the driving field becomes longer, the amplitude and the stationary value increase
