Development of high performance optical coatings for laser systems

High performance optical coatings are essential for the laser systems. To increase the performance of the laser coatings, including optical and mechanical properties, as well as the laser induce damage resistance, many efforts have been done. The developments of the coating design, deposition process and post treatment process, as well as the understanding of mechanical and laser damage mechanism have promoted the advance the laser coatings, various coatings with high performance have been developed.
