Abstract

The objective of this paper is to analyze two marking laser systems and to discuss the possible industrial applications of laser techniques; the first uses a diode pumped Ytterbium fiber laser and the second a pumped flash light Nd:YAG. Starting from the phenomena of heating due to laser irradiation and the spatial profile of deposited energy we try to explain the marking technique, including the laser-assisted coloring by studying the dynamics and the evolution of the parameters involved in this process. Also we emphasize the industrial importance of the laser possibilities compared to classical methods.
