Dichroic beam splitters are widely used in multi wavelength laser systems, and their scattering loss affects the signal-to-noise ratio and performance of the system. In this study, we investigate forward and backward scattering induced by nodular defects in a dichroic beam splitter. The seed size, seed position, and geometric constants of nodules exhibited distinct effects on the scattering characteristics. The modeling and simulation provide valuable insights into the relationship between the structural parameters of nodules and their scattering characteristics, offering practical guidance for various high-performance optical multilayer coatings and systems.
分色光束分离器广泛应用于多波长激光系统中，其散射损耗会影响系统的信噪比和性能。在本研究中，我们研究了分色光束分离器中结节缺陷引起的前向和后向散射。结节的种子尺寸、种子位置和几何常数对散射特性有明显影响。建模和仿真为结节的结构参数与其散射特性之间的关系提供了有价值的见解，为各种高性能光学多层涂层和系统提供了实际指导。
