摘要
采用线性化近似方法计算了在由色关联噪声驱动的单模激光中加入信号后的光强关联函数.结果表明,在噪声为短时关联时,光强关联函数为等幅振荡的,其振荡包络线可以是单调的,也可以是单极值的,还可以是双极值的;在噪声为长时关联时,光强关联函数为等幅振荡的,其它络线是水平的.
By using the linear approximation method, the intensity correlation function is calculated in a gain-noise model of a single-mode laser input signal and driven by colored cross-correlated pump noise and quantum noise. The behavior of the intensity correlation function versus the time is discussed.In short noise correlated time, the curse are vibration;the wraps besides decreases monotonously and exhibits several cases, such as one maximum, one minimum, and two extrema (one maximum and one minimum).In long noise correlated time, the wrap is invariable.
