Abstract

To study the thermal damage process of optical film induced by continuous wave lasers, a model with contaminants on the surface of optical film is established. Based on the temperature field theory and heat conduction theory, we apply finite element method (FEM) to calculate the thermal damage process of the optical films. The results show that contaminants on the surface play an important role in the damage process of optical film. Finally, we compare the calculated results with our experimental data, and the calculated thermal damage process of film is in agreement with our experimental record.
