| 摘 要： | 利用线性近似，研究了交叉关联噪声对具有饱和效应的单模激光模型动力学性质的影响，导出了平均光 和强度关联函数的表达式，发现：①在阈值以上，平均光强不受交叉关联噪声影响；②强度关联函数随噪声关联强度η的增加而增加。

| Abstract: | By linear approximation,the dynamical properties of the loss-noise laser model with saturation effects driven by correlated additive and multiplicative white noise are investigated.The analytic expressions of the mean intensity and intensity correlation function of the laser model are derived.It is found that:①the mean intensity is not influenced by the correlated noises when the laser is well operated above threshold;②the intensity correlation function increases as the coupling strength η increases;That is,the coupling between noise terms slows down the decay of intensity correlations in the laser field. |
