对单模激光增益模型的光强方程加入调幅波,用线性化近似方法计算了以e指数形式关联的两色噪声驱动下光强的输出功率谱及信噪比.结果表明噪声间互关联时间及互关联程度对随机共振影响很大,信噪比随着载波信号频率ω和调制信号频率Ω的变化也和白噪声的变化曲线有很大不同.
The output power spectrum and signal-to-noise ratio of light intensity driven by two-color noises were calculated by using the linearized approximation method for the light intensity equation of the single-mode laser gain model.The results show that the inter-noise correlation time And the degree of mutual correlation have a great influence on the stochastic resonance. The signal-to-noise ratio varies greatly with the variation of the white noise with the change of the carrier signal frequency ω and the modulated signal frequency Ω.
