| Abstract: | Research progress of laser induced damage of coating at 193nm was reviewed. After some typical damage morphologies from UV to DUV were compared, the possible reasons for the laser damage of the coating were put forward. The absorption of oxide coating at 193nm was responsible for the massive damage, while the damage of fluoride coating at 193nm was induced by local deposit defects. The dependence of the laser induced damage threshold on the thin film preparation parameters was known according to the damage analysis of the specimen. The methods to enhance the laser induced damage threshold were summarized by material chose, coating design and deposition process. |
