Properties of the Surface of Structural Materials in the Area of a Barcode Formed under the Action of Laser Radiation

This article presents a review of experimental investigations of changes in the structure and properties of the surface and near-surface layers of various materials (steels, metal alloys, ceramics, and graphite) in the area of a barcode applied by continuous laser radiation and short (nanosecond) and ultrashort (femto- and picosecond) laser pulses.
