ABSTRACT:
The method for decorative processing is performed with repetitively pulsed cross discharge at atmospheric pressure by CO.sub.2 -laser with pulse energy 1 to 5J, power density at operation from 1.10.sup.6 W/cm.sup.2 to 6.10.sup.7 W/cm.sup.2, pulse duration from 50 to 100 ns and average power 1 to 1000W whereby the mated area with one shot is from 0.5 to 2 cm.sup.2.
The device for laser engraving comprises a base with mounted console, on which are fastened parallel elements and a screw that is seated in its upper end in a thrust and in its lower end it is linked by a hinge to an electric motor. There is a fork which is seated in parallel elements whereby to this fork by means of handle and fixator is fastened a slide with longitudinal channels and a plate for axial inclination per 15.degree.. To this slide is fastened a second electric motor, and on its axis is mounted a bearer on which is fastened a mask in which is fixed the item to be decorated. On the rotating bearer is fastened a disk on which are mounted 4 spokes with 4 springs and a replaceable stand.
