非线性光学 受激布里渊散射 宽带激光 能量反射率 nonlinear optics stimulated Brillouin scattering broadband laser energy reflectivity
摘要
提出了一个描述宽带激光抽运受激布里渊散射的理论模型.假设宽带的连续激光光谱是由若干窄带的光谱组成,这些相邻窄带谱线产生SBS的过程有一定的耦合作用.模型中包含抽运耗空和介质击穿对SBS过程的影响.理论和实验获得了宽带抽运对SBS过程影响的基本规律,获得的最大能量反射率为45%.数值拟合的结果与已有实验结果进行了比较,理论与实验基本吻合,证明了模型对宽带SBS的产生有一定的预测作用.
Abstract
The paper presents a theory model to describe the process of stimulated Brillouin scattering (SBS) pumped with broadband laser. The mode is assumed that the broadband spectral is made of many narrow bands. It considers the effect of pump depletion and optical breakdown on SBS. The maximum reflectivity of 45% is got in experiment The theoretical results are consistent with the experiment.
