The aim of this work is to study in detail the drilling process on glass by CO2 laser. The study parameters considered in the present experiments are based on the laser beam power of range (30% -80% of 25 W) and an exposure time for drilling (2 -8 s). The measured diameters of holes by optical methods are between [300 -800 µm]. The results obtained by optical observations suggest that ordinary and mineral glasses cannot withstand to a contact of the laser beam and crack during the formation of the drilling hole. The minimum power and duration of exposure are the optimal parameters for drilling the organic glass, we observe no micro-cracks, and again we see that the edges of the holes have a good surface quality with a high aspect ratio.
Abstrait. De toutes les grandeurs physiques, la température est certainement l'une de celles dont la mesure est la plus fréquente, la température détermine en effet de façon décisive les propriétés de la matière, c'est pourquoi, on recherche comme dans l'industrie et les laboratoires,
