| 摘 要： | 从理论上对加性噪声和倍增噪声之间有耦合作用的一维激光模型进行了分析，发现耦合的性质对激光场涨落影响较大，噪声之间的正耦合会延缓强度相关函数的衰减，增强激光系统的统计涨落。噪声之间的负耦合能抑制激光系统的统计涨落，提高激光场的相干性，使激光系统由随机过程向确定过程过渡。

| Abstract: | The effect of positive and negative coupling between additive and multiplicative noise terms in a laser field is investigated. The fluctuations in the laser field is related to the property of coupling. The positive coupling between noise terms slows down the decay of intensity correlations, thus enhances the fluctuations in the laser system. While the negative coupling suppresses the fluctuations in the laser system and changes the system from stochastic process to deterministic process. |
