英文摘要：

A laser damage test platform for optical film is designed. The damage threshold is tested and evaluated through the image detection and laser scattering. The system consists of a laser, beam expander, attenuator, scattering detector, optical detection, CCD, etc. Laser damage of SiO2 thin film threshold is tested, the thin film is prepared by sol gel method. The experiments show that this test platform can accurately measure the damage threshold and provide ef- fective means to study laser damage of the thin film.
