ABSTRACT:
Method of cutting a glass piece along a predetermined cutting line. One and the same beam of laser rays, focused by a focusing device, travels along the predetermined cutting line during at least one marking step and during at least one heating step, the focusing device being an adjustable focusing device which, during a marking step, focuses the beam of laser rays substantially on the predetermined cutting line and which, during a heating step, ensures that the focal point of the beam is appreciably distant from the predetermined cutting line.
