Abstract: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 hol… Show more
