METHOD FOR CUTTING CHEMICALLY STRENGTHENED GLASS

摘要

A method for cutting chemically strengthened glass is provided. The chemically strengthened glass includes a first stress layer, a second stress layer, and a tension layer sandwich between the first stress layer and the second stress layer. The method includes: using a green pulsed laser to cut the first stress layer, wherein the green pulsed laser includes a first green pulsed laser having femtosecond level and a second green pulsed laser having nanosecond level; using a ultraviolet pulsed laser to cut the tension layer, wherein the ultraviolet pulsed laser includes a first ultraviolet pulsed laser having femtosecond level and a second ultraviolet pulsed laser having nanosecond level; and using the green pulse layer to cut the second stress layer.
