Paper Abstract

The high energy laser put forward higher requirements about resistance laser damage ability of thin film on surface of optical component, this makes coating film not only consider the optical parameters of thin films, but also consider the film’s laser damage threshold to get the optical system work normally. mainly analyzing factors about effecting the SiO2 thin film’s laser damage threshold and researching respectively the SiO2 thin film’s optical parameters (such as extinction coefficient, thickness, refractive index and so on) and light sources parameters of testing system (such as laser times of irradiation, pulse width and so on) impact on thin film laser damage threshold. Research shows that thin film optical parameters have little influence on laser damage threshold, testing laser parameters have great influence on laser damage threshold.
