Abstract: A method and system for laser pre-cutting a layered material (31) with a laser beam (14) is disclosed. The layered material (31) comprises at least one tensile stress layer (TSL), at least one compression stress layer (CSL1, CSL2), and at least one interface region (IR1, IR2) between the at least one tensile stress layer (TSL) and the at least one compression stress layer (CSL1, CSL2) and is transparent to allow propagation of the laser beam (14) through the layered material (31).
