The basic factors affecting the laser marking of products – volumetric density of the absorbed energy and the number of repetitions, were studied. Experiments were conducted of marking the samples of stainless steel with fiber laser. The dependence of the contrast of marking from the power density for different number of repetitions, and also the volumetric density of the absorbed energy from speed was obtained and the experimental results analyzed.
