  • Patent number: 4866244
    Abstract: An arrangement for machining material by means of a laser beam includes a laser and an exit window mounted between the laser and the workpiece to be machined. The exit window is made of a highly-interlaced plastic to substantially prevent a contamination of the window by means of material splatterings during the machining operation. The highly-interlaced plastic has a high elasticity in microscopic regions. Such a window made, for example, from allyldiglocylcarbonate has a long service life which extends to several days in automatically operating equipment for spot welding with a laser beam.
