窗函数关联噪声对单模激光动力学性质的影响

Effect of Rectangular Function Correlated Noises on Dynamic Properties of a Single-Mode Laser

应用线性近似方法 ,计算了具有窗函数形式关联的两白噪声驱动下单模激光光强的关联函数、功率谱及关联时间 .根据计算结果讨论了窗函数的高度和宽度对以上各量的影响 ,并和噪声间具有δ函数关联形式的情况进行了比较 .

The expressions for correlation functions, power spectrum and correlation time of the intensity of a single_mode laser driven by two white noises with a rectangular function correlation form are calculated by linear approximation method. According to the calculated results, the effects of the width and height of the rectangular function on the above quantities are discussed and compared with the situation of a delta function correlation form between noises.
