对具有色泵噪声和白量子噪声关联驱动的单模激光模型的稳态统计性质进行了研究。从交叉关联噪声驱动的修正郎之万方程(MLE)出发,利用近似福克 普郎克方程(AFPE),计算了稳态激光光强的平均值、斜方差λ2(0)和偏斜率λ3(0),并分析了泵噪声的“颜色”对它们的影响。研究发现:1)泵噪声的自关联时间τ与量子和泵噪声的交叉关联强度λ对分布函数Pst的影响是完全相反的;2)τ基本上不影响平均光强,但在阈值附近,λ会使的涨落增加;3)λ和τ对λ2(0)和λ3(0)的影响是一样的。
The steady state statistical properties of a single-mode laser model driven by color pump noise and white quantum noise are investigated. Based on the modified Langevin equation (MLE) driven by cross-correlated noise, the mean value of steady-state laser light intensity , the skewness λ2 (0) and the bias Slope of λ3 (0), and analyzed the effect of pump noise on the “color” of them. The results show that: 1) the cross-correlation intensity λ of pump noise self-correlation time τ with quantum noise and pump noise has the opposite effect on the distribution function Pst; 2) τ does not affect the average light intensity In the vicinity, λ will increase the fluctuation of ; 3) The influence of λ and τ on λ2 (0) and λ3 (0) will be the same.
