    Abstract: A simultaneously super pulsed Q-switched CO2 laser system for material processing is disclosed. The system comprises sealed-off folded waveguides with folded mirrors that are thin film coated to select the output wavelength of the laser. The system also comprises a plurality of reflective devices defining a cavity; a gain medium positioned within the cavity for generating a laser beam; a cavity loss modulator for modulating the laser beam, generating thereby one or more laser pulses; a pulsed signal generation system connected to the cavity loss modulator for delivering pulsed signals to the cavity loss modulator thereby controlling the state of optical loss within the cavity; a control unit connected to the pulsed signal generation system for controlling the pulsed signal generation system; and a pulse clipping circuit receptive of a portion of the laser beam and connected to the pulsed signal generation system for truncating a part of the laser pulses.

    Abstract: A device for treating a substrate with laser radiation is described. The device has a rotating polygon mirror with N reflecting surface which are used to direct a laser beam via a system of converting focusing lenses, whereby the focal planes of the lenses are located on a surface of the substrate. Active reflecting surfaces direct the laser beam onto the converging lens system, and subsequently on the substrate, while inactive reflecting surfaces have a different inclination to the active reflecting surfaces in relation to the converging lens system. The laser beam from the surfaces is directed onto an absorber. The large number of inactive reflecting surface helps to reduce serial hole density. When the laser is switched on an off while the inactive reflecting surfaces are being scanned, further reduction of serial hole density can be achieved.

    Abstract: A hinge lid container (10) for consumer articles comprises a box (12) and a hinge lid (14) connected to the box along a hinge line and pivotable about the hinge line between a closed position and an open position. The hinge lid comprises a first lid wall (16) and a lid flap (18) depending from the first lid wall along an edge fold line, the lid flap being folded inward towards the inner surface of the first lid wall. The container is at least partially formed from a blank having a thickness (T), the laminar blank defining an edge fold portion of the container connecting the first lid wall and the lid flap. The inner surface of the edge fold portion defines an ablation area (A) having a length in the longitudinal direction of the edge fold portion and a width (W) extending transversely to said length.

    Abstract: A method is for cutting machining of a workpiece using a laser beam. The method includes (a) directing the focused laser beam onto a surface of the workpiece for a formation of a kerf; and (b) removing a material exclusively by ablation. The laser beam has a power density in a focal point of at least 1*107 W/cm2. The laser beam has a feed speed taking account of an absorption capability of the material to be removed of at least 150 m/min up to a maximum of 1200 m/min.
