利用线性近似方法推导了由e指数关联噪声驱动的单模激光他和损失模型、增益模型和损失模型的光强关联函数和功率话，讨论了激光模型中的地和效应，得到了一些有意义的结论．①在一定条件下，光强关联函数随时间演化会出现负极小值，而功率增随频率的变化会出现双峰；②激光模型中的确定论饱和项使激光的统计性质产生明显的变化，而随机炮和项则掩盖了这种变化．
The linear correlation method is used to deduce the light intensity correlation function and power of the single-mode laser, the loss model, the gain model and the loss model, which are driven by the e-index correlation noise. The ground effect in the laser model is discussed and some meaningful Conclusion. (1) under certain conditions, the light intensity correlation function evolves with a small negative value over time, and the double peak appears with the increase of power with frequency; (2) the deterministic saturation term in the laser model changes the statistical properties of the laser obviously, Random gun and item mask this change.
