Diploma work presents laser markings on stainless steel together with the influence of basic parameters on black markings. In the thesis we tried to obtain the optimal parameters in laser system which ensures sufficient contrast markings. They were produced with laser system consisting of a fiber laser, laser scan head, laser system interface and laser positioning system. Samples were matrix-assisted meaning that laser power, laser light length and overlapping were changing. All the samples were performed on stainless steel AISI 304 1.5 mm thickness. Results were evaluated according to marking contrast and roughness and presented together with marking parameters. The results obtained enabled us to label our application as well as to search for the system that provides production of adequate black markings.
