| 摘 要： | 通过对含Langevin项噪声源的多模速率方程的分析，利用状态空间法得到光强噪声及其自相关函数的分析解；用数值方法计算了开启瞬态主模及第一边模的光强噪声及其自相关函数。计算结果表明，主模的光强噪声在开启瞬态主要表现为开启颤抖时间，边模的起伏表明开启瞬态容易引起边模效应。

| Abstract: | Analytical solution to rate equation with Langevin noise is described by a state-space method. The numerical calculations of the variance and the autocorrelation function of the transient intensity noise in main mode and in the first side-mode are carried out. It is shown that a significant part of the nonstationary intensity noise can be described as timing jitter of the relaxation oscillation and the events transient side-mode fluctuation easily takes place. |
