摘　　要：从电偶极近似和旋波近似下开放的V型无反转激光系统的密度矩阵运动方程出发 ,利用数值计算方法研究了探测场和驱动场失谐情况下系统原子响应的瞬态演化规律 ,并与探测场和驱动场皆共振时的情况进行了比较 ,我们发现失谐对原子响应的演化规律有显著影响 .Starting from the motion equations of the matrix density of the system under the rotating wave and dipole approximations,we study instantaneous evolution of the atomic response in an open v-type inversionless lasting system when the probe or drving flied is off-resonance by the numerical results,and compare the evolution law with that obtained when probe and driving fields are resonant.We find that the detuning has considerable effects on the evolution law.
