Abstract

In the detection of the temperature rise of the reflective element, due to the lack of effective numerical simulation methods, the test is carried out by the measured method, resulting in a large loss of time and economy. Therefore, an accurate and effective numerical analysis method is needed to estimate the temperature change of the element under laser irradiation. This paper firstly conducted a temperature rise experiment on a reflection mirror plate of a specific film system under 1030 nm wavelength laser irradiation; secondly, the reflection mirror was modeled and numerical calculations were analyzed to determine the size of the boundary conditions for numerical analysis; finally, the effects of film system structure, air convection coefficient, and convection mode on the temperature rise of the mirror plate under laser irradiation were explored. The results show that the method proposed in this paper can accurately simulate the temperature change of specific film mirrors under continuous laser irradiation. The film structure has a great influence on the temperature, and the error is 47.4 %. The air convection coefficient and different pairs of manifolds have a great influence on the temperature change during long-term irradiation, and have little effect on the temperature in a short time, which can be ignored.
