摘要
采用信号直接调制色泵噪声的单模激光增益模型,用线性化近似方法研究了反映激光动力学统计性质的光强相关函数,发现泵噪声的自关联时间相当于力学中阻尼振荡的阻尼系数,它的大小决定光强相关函数随时间t的演化形式．
Adopting the linear approximation method, we have studied the intensity correlation function in a gain-noise model of single-mode laser by pump noise with signal modulation, and have found that pump noise self-correlation time is similar to that in mechanics damping coefficient of damping vibration, and the time evolution of intensity correlation function depends on pump noise self-correlation time.
