将周期信号输入双模激光,对激光光强方程中的乘法噪声项取一级近似,用线性化近似方法计算相关函数和功率谱,结果发现:信噪比随抽运噪声强度、量子噪声强度及信号频率的变化均出现随机共振.
The periodic signal is input into the dual-mode laser and the first order approximation of the multiplicative noise in the laser intensity equation is obtained. The correlation function and the power spectrum are calculated by the linear approximation method. The results show that the signal-noise ratio varies with the pumping noise intensity, the quantum noise intensity And the signal frequency changes appear random resonance.
