Abstract

In order to evaluate the performance of the low absorption thermal Control coatings, the laser induced damage behavior of coatings was studied with 1064 nm at different power densities. The damage properties were characterized by scanning electron microscope (SEM) and X-ray diffraction spectrum. The results show that the specimens of both A-1 and A-2 can be damaged by the laser. Combined with the temperature effect, the effect of infrared emissivity of the coating to the damage behavior of the two specimens is mainly due to the temperature effect by infrared emissivity and stacked structure.
