Abstract

Laser damage is becoming more and more important part to consider in design of laser systems among these decade years, for high-power lasers are widely used in industry production, medicine, signal detection, and any other departments. There are two research directions of laser damage: one is the damage caused by ultra-short pulse, the other is that caused by ultraviolet beams. These two types of laser are usually combined to irradiate materials. Laser Induced Periodic Surface Structures (LIPPS) are special phenomena which can change many physical characters of materials, for example, surface absorptivity. LIPPS are usually caused by ultra-short pulse, as a step of laser processing. This paper will reveal the damage caused by ultra-short and ultraviolet beams, especially when they lead to LIPPS.
