| 摘 要： | 根据线性化的单模激光输出光强方程，直接计算光强的相关函数，得到光强的功率谱及信噪比的方法，计算了具有δ函数形式关联的两白噪声驱动的单模激光线性模型在输入信号后其输出信噪比，发现了随机共振现象，根据计算结果讨论了噪声强度和噪声间互关联程度对信噪比的影响，由于推导用的是精确解析表达式，因此所有参数不受限制，可以探讨近似方法适用范围外的规律。

| Abstract: | Calculating the correlated function of the laser intensity according to the linearized equation of single-mode laser, we detected stochastic resonance (SR) phenomenon by studying the output signal-to-noise rate (SNR) of the linear model of single-mode laser driven by two white noises correlated in the form of a function. were discussed The influence to SNR by additive noise intensity and correlated coefficient between both noises. The results are exact and all the parameters are not limited. That method it can be used to investigate the action out of the range of the approximative methods. |

| Keywords: | noise correlation form single-mode laser signal-to-noise rate stochastic resonance |
