Abstract

Surface of solids play a leading role in any process of interaction between solids, solids-liquids, solids-gases and solids-plasma. Microgeometry 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: (i) surface microstructuring and control of roughness by laser ablation; (ii) surface microstructuring based on creation of surface electromagnetic waves (SEW) and surface periodic structures (SPS); (iii) surface smoothing and microstructuring based on laser heating til 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.
