Effects of Multiplicative Noise and Injected Signal on First-order-Like Phase Transition in a Laser System

从含有注入信号的单模激光场的增益-噪声模型出发,得出激光场的定态强度分布函数。讨论了不同乘性噪声取值下的单模激光场一级相变参数区域图的变化,并给出了定态强度分布函数关于光强和注入信号关系的三维变化趋势图。

Starting from the injected signal noise of single-mode laser gain-noise model,this article derives a steady state intensity distribution function in laser field.Under the different values of multiplicative noise,it discusses the changes of the regional plan for single-mode laser field with one-order phase transition parameters.Moreover,3-D transition trendline of steady state intensity distribution function on the relationship between the light intensity and the injected signal field are proposed.
