讨论了限制在光学腔中的 V 配置中的三能级原子的时间相关处理，以及在存在和不存在非线性镜的情况下两种不同状态下的腔场动力学。采用矩阵连分数法求解瞬态无限耦合运动微分方程。在推导数值拉普拉斯逆变换时，应用了商差算法和快速傅立叶变换。描述了系统随时间演化的非线性效应，包括粒子数反演、平均光子数和一些无量纲参数的二阶相关函数。最终在特定条件下和弱驱动极限下将三能级原子还原为有效的两能级原子。
The time-dependent treatment of a three-level atom in theVconfiguration confined in an optical cavity as well as the dynamics of the cavity field in two different regimes, in the presence and absence of the nonlinear mirror, has been discussed. The time-dependent infinite coupled differential equations of motion are solved by the matrix continued fraction method. In deriving the numerical inverse Laplace transform, the quotient difference algorithm and the fast Fourier transform have been applied. The nonlinear effects of the system over the time evolution of the population inversion, the mean photon number and the second-order correlation function for some dimensionless parameters are delineated. Ultimately the reduction of the three-level atom to an effective two-level one under specific conditions and in a weak-driving limit has been performed.
