摘要: 为了开展激光吸收涂层性能研究，建立了激光加载吸收涂层样品模型，根据材料物性参数模拟了激光能量耦合过程，分析了不同参数激光加载条件下的温升情况。对铜基底表面碳氮化硅涂层开展了反射特性研究，并通过激光辐照实验，开展了涂层样品的抗激光损伤技术研究，得到了强激光辐照下涂层的温度阈值。本文的研究内容为激光能量测量装置涂层选材及参数设计提供了技术支持。Abstract: A laser loading model for coating samples is established for studying the performance of laser absorbing coating. The coupling process of the laser energy is simulated based on the parameters of the materials and the temperature rise characteristics are analyzed at different parameters. The reflective characteristics of SiCN coating on a copper substrate are then investigated. Through a series of laser radiation experiments, the laser-induced damage of the coating is examined by recording the temperature threshold for the coating. This paper provides research support for the material selection and parameter design of laser energy measurement devices.
