Theoretical and experimental studies on the intensity distribution under Bragg diffraction by acousto-optic devices
摘要
本文在一维布喇格衍射分析方法的基础上,导出了两维时的衍射场光能量分布,给出了相应的实验结果.分析了影响衍射光光斑能量分布的主要因素,最后提出了综合考虑衍射效率,上升时间、光斑形状的新的设计思想.
Abstract
On the basis of one-dimensional Bragg diffraction analyzing method, a 2-D intensity distribution of diffraction field is derived. The experimental results are given. The factors which inflnenoe the intensity distribniion of diffracted light spot are discussed. A new idea for designing the shape of diffracted light spot is proposed,, in which the diffraction efficiency, rise time and light spot shape are all considered.
