Study On Anti-Laser High-Reflection Coating

Multi-layer dielectric high reflecting mirror is one of the important optical elements of laser. In terms of high power laser, anti-laser damage threshold value of high reflection coating which deposit on the surface of the optical component affect the life of laser system directly, so we deeply study the damage mechanism of multi-layer dielectric highly reflecting film under the exposure of laser. Choose suitable film material and adopt the manufacture method of complex film. Through multiple experiments and optimize the parameter, we find the path of improving anti-laser damage threshold value of film and the method of making high intensity film. The results of experiment and testing turn out that the film manufactured completely meets the demand of laser system used in the subject.
