单模染料激光色增益模型的统计性质

THE STATISTICAL PROPERTIES OF THE COLORED GAIN MODEL FOR SINGLE-MODE DYE LASER

简要地概括了具有加法色噪声系统的定态几率分布统一展开理论，并将其推广应用到乘法色噪声驱动系统，计算了单模染料激光色增益模型的光强定态几率分布，发现用统一展开理论所得到的结果明显地改善了用最佳福克一普朗克方程近似和统一色噪声近似两种方法所得到的结果而与实验结果更加符合．

A unified expansion theory that can be simultaneously applied to bothlarge and small correlation times is introduced briefly at first, and then it is appliedto calculate the stationary intensity probability of colored-gain-noise model for dyelasers. We compare the results of the unified expansion theory with the predictionsof the best Fokker-Planck equation and the unified colored-noise approximation forthe stationary intensity probability of a colored-gain-noise model and find that theresults of the unified expansion theory agree better with simulation and experimentresults than the results of the best Fokker-Planck equation and the unified colorednbise approximation.
