摘要

Surface of solids play a leading role in any process of interaction between solids, solids―liquids, solids―gases and solids―plasma. Microgeometry (roughness) is a key parameter of the solids surface which influence a lot mechanical, optical, electronic, chemical, thermical and other characteristics. Nowadays the laser―based technologies is a great challenge to improve a surface microgeometry (SM) quality and controllability. Different laser―based surface processing are considered: 1. surface microstructuring and control of roughness by laser ablation, 2. surface microstructuring based on creation of surface electromagnetic waves (SEW) and surface periodic structures (SPS), 3. surface smoothing and microstructuring based on laser heating till melting and further phenomena in a melted phase. Some examples of laser applications to improve optical, tribological and other surface characteristic are considered and analyzed. Future prospects of this field are discussed.
