Research Progress in Surface Micro-nano Structure of Materials Prepared by Ultrafast Laser

Ultrafast laser has the characteristics of short pulse width and high peak power. Compared with the long pulse, the thermal effect on the material is almost zero, which makes the use of ultrafast laser processing materials gradually paid attention to by the scientific community. This article reviews the mechanism of micro-nano structures produced on the surface of ultra-fast laser irradiation materials, and summarizes the main characteristics and performance of micro-nano structures on the surface of ultra-fast laser prepared materials. The two aspects of the processing technology are discussed, the formation of the surface structure of the material, the performance and the research conclusion are explained, and the advantages and disadvantages of each process are discussed. Finally, the latest development trends of ultrafast laser preparation of biomimetic functional surface and biomedical material surface are summarized, and the problems encountered in the future research and development of ultrafast laser preparation material surface micro-nano structure are prospected.
