Paper Abstract

Using a CO2 laser beam steered by a X-Y galvanometric scanner, alphanumeric characters, geometric figures or complex pictograms were marked on different target materials, with a special emphasis given to leather samples. Laser and scanner operating parameters are evaluated regarding the laser interaction with biological tissues. The developed set-up and associated software structure for generating and marking images in different scanning modes are presented. The experimental results present samples of leather of various qualities marked by a low-power CO2 laser beam, swept with marking speeds in the range of (100-300)Bit/ms.
