摘要：

Laser-induced damages in several reflection coatings that are prepared with variant materials and technologies are investigated. It is found that the damage thresholds of the coatings are very difference depending on the impurity absorption. We proved this conclusion by applying Auger Electron Spectroscopy to determine the surface composition of the coatings and measuring of the absorption of these coating. Laser condition of a larger size coating is realized through scanning of a smaller laser spot. The condition is achieved through roistering at ten steps increasing from 5 to 80% of the zero probability damage threshold of the coating. The effect of the laser condition is directly related to the preparation process and the materials of the coating.
