METHOD AND DEVICE FOR STRUCTURING OF SURFACE OF SOLID BODY COATED WITH SOLID MATERIAL WITH HELP OF LASER Russian patent published in 2016 - IPC B23K26/362 B23K26/66 B31F1/07 

FIELD: process engineering.

SUBSTANCE: claimed invention relates to structuring of the surface (9) of solid body material applied thereon and to packing foil embossed by appropriate stamps or rollers. The structure is made on at least one area of solid body surface with coating ta-C. For this, template (18) is used in homogeneous spot (FS) of optical system to shaped the beam by template projection along with diaphragm (6) arranged ahead of display optics. Said structure is produced with the help of excited-state dimer laser with pulse duration of nanosecond (1) to use some quantity of combinations of templates and diaphragms (18, 6) fitted in exchange device (28). The latter can house one of said templates (18) and one of diaphragms (6) in laser beam path arranged independently. Templates (18) and diaphragms (6) are fitted in the holders and can revolve about their axes and translate.

EFFECT: optimised production of complicated coloured specimens protected against counterfeit.
