本文对具有加性和乘性白噪声关联的单模激光模型的统计性质进行了研究.从一个具有交叉关联噪声与单模激光与立方模随机等价郎之万方程,计算了稳态激光光强度的平均值、协方差和偏斜率.并与早期结果比较,阐明了考虑郎之万方程修正项对描述激光系统统计性质的重要性.

The stationary properties of a singlemode laser with correlations between additive and multiplicative whitenoise terms are investigated.The mean,variance,and skewness of the steadystate laser intensity are calculated through a Langevin equation(LE) derived by Long which is always stochastically equivalent to the single mode cubic laser model when additive and multiplicative noises are correlated.Compared with the result obtained by Zhu,the consideration of modification item in LE when addivtive and multiplicative noises are correlated is important for describing statistical properties of the laser system.
