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δ函数形式关联的两白噪声驱动下光强的输出功率谱及信噪比.结果表明,信噪比不但随着抽运噪声和量子噪声强度的变化出现随机共振,而且随着高频载波信号频率和低频调制信号频率的变化也出现了随机共振.
The output power spectrum and signal-to-noise ratio of light intensity driven by two white noises correlated with δ function were calculated by the linearized approximation method for the light intensity equation of the single-mode laser gain model.The results showed that the SNR Stochastic resonance occurs with the variation of the pumping noise and the quantum noise intensity, and also with the frequency of the high-frequency carrier signal and the low-frequency modulation signal.
