A mathematical model of the thermal degradation of semiconductor infrared optical materials under continuous near-infrared laser irradiation has been established, which contains the physical processes of temperature field changes and transmittance changes during the laser heating of the materials. The main physical quantities related to the model for three materials, Ge, Si and GaAs are studied comparatively, and the thermal degradation of infrared optical windows made from these three materials under laser irradiation is simulated using the model respectively, and the results are compared. The image blinding effect due to laser-induced thermal degradation of the above three windows is presented using the imaging system simulation software.
