  2. 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

    研究了探測場或驅動場失諧情況下開放的型無粒子數反轉激光系統中原子響應的時間演化規律，並與探測場和驅動場都共振時的演化規律進行了比較.我們發現失諧對時間演化規律有顯著的影響;當驅動場或探測場失諧時，原子對探測場和驅動場色散的響應不再為零，雙光子相干不再是純實量;探測場失諧的變化將使粒子布居和驅動場增益（吸收）的時間演化規律明顯改變;隨著失諧的增大，探測場增益（吸收） 、色散和雙光子相干隨時間的演化行為逐漸偏離標準阻尼振子的演化規律;驅動場色散驅動場失諧量的增加而振蕩時間變長，振幅和穩定值變大

  12. The analytical solutions of the gain, dispersion and population difference in the steady state of an open ladder lasing without inversion ( lwi ) system are at first given when the phase fluctuation of the driving field is considered. then the effects of the driving field phase fluctuation on the gain, dispersion and population difference are analyzed by the numerical results from the analytical solutions. our research shows that the phase fluctuation of the driving field will results in a finite line width ; with the line width increasing, the gain decreases monotonously, however, variation of the dispersion isn ? t monotonous, it has a maximum value when the line width takes some value ; the line width varying can ? t lead to change lasing from without to with population inversion
