| Abstract: | In this paper, the damage equation of laser separation membranes at a wavelength of 1064 nm was established, based on the thermal damage principle of laser separation membranes, and a damage threshold of the solution process was presented. Besides, the damage characteristics of SiO2 thin film which was caused by the laser at 1064 nm were analyzed in theory, and the distribution curve was gained by the method of simulation, which showed the change of temperature field in the thin film along with the difference of impurity position in the process of laser radiation. |
| Keywords: | laser thin film materials temperature field damage threshold |
