High-power laser systems and equipment have a significant impact on the solution of major scientific problems, the progress of the national defense equipment, and the development of the high-tech industries, whose core components as well as the weakness are the laser coatings. The research group built a development platform that includes the optimization design of laser coatings,all-flow-control preparation, performance characterization, and system application. They studied the interaction mechanism between the laser and materials and explored the loss mechanism and control techniques of laser coatings. An effective regulation of the coating structure, optical properties, and environmental adaptability has been achieved, which contributes to the development of the high-power laser system.
The laser coatings with a high damage threshold fabricated by the research group reached the international advanced level. In addition, the transformation of the patented technology in high-power laser coatings has been achieved, thereby eliminating the bottleneck in the development of high-power laser technologies and devices in the country. This has demonstrated to be critical for large scale scientific facilities, national defense, aerospace engineering, and advanced manufacturing, and has successfully promoted industrial technologies, addressed major needs of the country, and helped training new talents.
