摘要：
Methods for laser beam cutting metal workpieces with a thickness between 4 mm and 25 mm. A double focusing lens is provided to make it possible to focus a laser beam on a first focusing and a second focusing point. These points are separate from each other and both lie on the laser's optical axis. The lens has a focal length between 170 mm and 300 mm.
