杂散光可视化分析模型在高功率激光装置中的辅助设计和应用

针对高功率激光装置，基于自研鬼像追迹软件(GA)的鬼像分析结果，采用辅助设计方法在装置的三维结构模型中形象、直观地显示鬼像的分布情况，精确计算出鬼像光束传输过程中与装置的干涉情况；并对典型未知的鬼像危害进行分析，提出了可采取的规避措施。所开发的软件能够满足高功率激光装置不同要求的鬼像分析计算，其分析结果直接应用于装置的设计，对于缩短设计周期、提高光束质量、降低装置造价具有重要意义及明确的应用前景。

Abstract

According to the analysis of stray light in high power solid-state laser system, ghost image is 3D demonstrated in the structure model of the facility by ghost-analysis (GA) software. The simulation model to describe ghost-image distribution is also established. The position of the one-or-more-order ghost image in the facility can be fully displayed in all directions so that the ghost-image harm can be avoided. This paper takes some of the “dangerous surfaces” as example,simulating the energy distribution on it by tracing numerous real rays. According to the shape of ghost energy and its corresponding optical stucture, suggestions are made to effectively mitigate the damage on the srudied optical surfaces. This analytical result is in good accordance with that in practice. It is proven that such an analytical method has provided a detailed reference for mitigation of ghost-caused damage.
