摘要: The invention relates to a system for marking or perforating by laser and to a marking or perforation process in said system, which is comprised of at least one laser (19) which produces a beam, a supply unit for at least one laser (19), a control means (12) with a control program which controls the laser (19), a deflector (16) particularly an optical-acoustic deflector which produces different beam deflection angles, in this case an optical system traversed by the beam, which produces a marking or a perforation configured like a matrix of points (n.times.m) on a surface of a product in relative motion between the product to be marked or perforated and the laser beam. The supply unit and/or the deflector (16) may be controlled by the control program. The system of the invention provides for a dynamic control of the marking or perforation resolution in a vertical direction. ##STR1##
