Glass Marking with CO 2 Laser: Experimental Study of the Interaction Laser - Material

Abstract

Laser marking is a laser processing technology used in many fields of industry like automotive [1], aerospace [2], mi-croelectronic [3] and medecine [4]. CO 2 laser is an appropriate source for marking glasses [5]. Compared to the other techniques of marking, the principal advantages of the use of the laser are: made inalterable, high degree of accuracy and the smoothness of the features, the possibility of marking at difficult to reach places, and the fact of being able to mark fragile materials like ceramic and glass [6]. In this experimental work, the influence of marking parameters like interaction time laser-glass, laser power, shooting time etc. on the micromarking precision are reported. A "melt" depth prediction model has been established.
