| 摘 要： | 应用线性化近似方法计算了信号直接调制方式下由具有色关联的色泵噪声和色量子噪声驱动的单模激光增益模型的光强相对涨落，分析了噪声和调制信号等参量对光强相对涨落的影响，结果表明，泵噪声自相关时间与量子噪声自相关时间及其比值对光强相对涨落起到重要的作用．

| Abstract: | By using the linear approximation method, the normalized intensity fluctuation was calculated in a gain-noise model of a single-mode laser driven by colored correlated noises, and the influences of the parameters of the noises and modulation signal normalized intensity fluctuation were studied. The results showed that the normalized intensity fluctuation was strongly dependent on self-correlation times of the pump and quantum noises and the ratio of them. |
