| 摘 要： | 本文提出了一个描述单模染料激光光强随机变化的模型.该模型主要考虑了“饱和项”的色噪声和自发辐射量子色噪声的影响.运用“有效FPE”方法,得到该模型的有效FPE及光强定态几率分布P_(st)(Ⅰ).考虑稳定性条件和几率收敛条件,在两种极限条件下分析了两个不同Ⅰ_0值对应的类一级相变.通过计算机模拟,得到了P_(st)(Ⅰ)类型随参数的演化情况.

| Abstract: | A new model for describing the stochastic variation of the single-mode dye laser intensity is proposed. For the model, there are the colored noise saturation term and colored quantum noise term. By using the effective Fokker-Planck equation method developed by the second author, the effective Fokker-Planck equation for this new model and its intensity probability distribution are obtained. The stability condition and convergence condition are studied. The first-order-like transition is studied by computer simulation. |
