为了适应激光器的迅速发展，需要改进现有激光测量技术，设计能够满足功率密度1000 W/cm2、时长10 s激光辐照的新型激光防护面板，金属铝板表面采用等离子喷涂的方法制备了氧化锆(ZrO2)热障涂层作为激光防护面板。利用不同波长的激光光源开展了涂层表面反射特性的实验研究，测量了涂层表面反射率及漫反射特性。利用数值模拟计算了激光辐照下铝面板ZrO2涂层的热响应。最后，利用光纤激光器开展了热障涂层防护面板激光辐照实验，验证了带有热障涂层的防护面板较未加涂层的防护面板具有一定的隔热效果，为激光测量技术的发展提供了技术储备。

Along with the fast development of high power lasers, the corresponding measuring techniques should be improved to withstand the long time irradiation of high power density laser beams. An aluminum panel is coated with ZrO2 thermal barrier coatings (TBCs) using plasma spraying method as the high power laser proof. Diffuse reflection characteristics of the coating are investigated at different wavelengths. Finite element analysis is conducted to analyze the thermal response of the ZrO2 TBCs under the high power laser irradiation. Moreover, related experiments are carried out with high power fiber lasers, which demonstrat that the TBCs is an effective method for heat insulation.
