| 摘 要： | 应用泛函导数,对三次激光模型中包含的两种噪声用小近似进行计算,得到激光场的稳态分布,计算了相对方差.结果表明,两种噪声同时存在时,噪声关联时间对光强的平均影响微小,在高于阈值工作条件下,对相对方差的影响较大.

| Abstract: | Functional derivation is employed to analyze the two noises in the third-order laser model. The stationary distribution and the normalized variance are derived. It is shown that pump noise correlation time has limited influence on the mean light intensities when the two noises co-existent in the laser. However, pump noise correlation time has great influence on the normalized variance when the laser is operated above threshold. |
