Abstract

The invention relates to a method and an apparatus for making a multiple of identical engravings by means of a laser beam (2) in which the power of the laser beam is concentrated on a small spot on an object surface and in which the laser beam is deflected in at least one, but preferably two, dimensions by means of at least one rotatable mirror (3) controlled by a predetermined pattern so that a script or any other graphic design is generated by the laser beam on the object on which the script is to be applied. The incident laser beam is divided into a number of individual sub beams (2a, 2b; 2c, 2d, 2e) before the deflection and the individual laser beams are arranged to impinge upon the rotatable mirror (3) under different angles of incidence so that the angular difference between the individual beams defines the distance between the individual engravings.
