Marking of organic materials by CO_2 laser beam scanning

摘要

CO_2 laser beam scanning method was used for marking of organic materials (leather, paper, wood), both in continuous wave and in pulsed regime. The computer controlled X-Y galvanometric scanner and the software developed for this application control every parameter of irradiation and allow programmable marking of simple marks, logos, alphanumeric characters, filled text, codes, graphics, or highly complex drawings and images. The factors influencing the quality of the marking were analyzed and the irradiation conditions were optimized to produce marks on organic materials with a quality imposed by industry standards.
