FIELD: physics.
SUBSTANCE: invention relates to the method of surface marking of a mechanical part by a predetermined graphic pattern, comprising the action by a laser source of a single laser pulse on the outer surface of the part to be marked, wherein between the laser source and the outer surface of the part there is a stencil containing the predetermined graphic pattern, wherein the laser pulse has a surface capacity of, at least, 20 MW/cm2 and a duration of less than or equal to 100 ns.
EFFECT: simple and fast marking.
