Abstract

Obtaining sharp and sometimes special patterns on hard materials surfaces (texturing) is rather difficult by conventional procedures, which made the laser an attractive choice in this matter. Absorption of Nd:YAG's 1.06 micrometers radiation in most steels and ceramics, which are the common materials for textured surfaces, is good such that average power lasers can be used. In this paper we are concerned with the principal phenomena involved in the texturing process and with the sought of a simple mathematical model that will allow to choose right working regime, and make estimations about the system performances (speed, power consumption, etc.). Experimental data were obtained by using both a Electro-Optically Q-switched CW laser with an average power of up to 100 W and a pulsed free running laser with an average power of up to 100 W and pulse energy of up to 10 J. The experimental set-up includes an X-Y stage and two gold deflectors used to cover the entire surface.
