| 摘 要： | 本文由光学Bloch方程和密度矩阵方程出发,研究了二能级系统共振型简并四波混频(DFWM)的饱和效应,给出了DFWM信号强度与泵浦光强度的函数关系.饱和泵浦光强的大小取决于纵向弛豫时间T1和横向弛豫时T2.对理论结果与相应实验进行了比较,表明二者符合得很好.

| Abstract: | ith the optical Bloch equation and the density-matrix equations,the saturation effect of signal intensity has been studied for resonance degenerate four-wave mixing(DFWM)of two level system,and the signal intensity saturation behavior is obtained as a function of pump field intensity.The value of.the saturation pump intensity is determined by longitudinal relaxation time T1 and transverse relaxation time T2.The theoretical result coincides with experimental result. |
