  • Patent number: 10538453
    Abstract: A method for cutting thin glass, wherein the thin glass is heated with a laser beam along a path forming a cutting line moving along a forward feed direction, such that a crack propagates along the cutting line and cuts through the thin glass. The laser beam is formed by a beam-forming optic in such a way that the beam profile thereof has an elongated shape. The laser beam is orientated on the surface of the thin glass such that the longitudinal direction thereof is aligned in the feed direction. The elongated shape of the beam profile is asymmetric, such that the intensity course differs at the ends of the beam profile in such a way that the increase in intensity at the front end crossing the thin glass first is steeper than the drop in intensity at the opposite rear end.

  • Patent number: 10407336
    Abstract: A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.

  • Publication number: 20130209731
    Abstract: Methods and apparatuses for producing a multiplicity of holes in thin workpieces made of glass or glass-like materials and semiconductors are provided. The method includes directing multiple laser beams onto predetermined perforation points of the workpiece in a wavelength range between 1600 and 200 nm and with a radiation intensity that causes local non-thermal destruction of the workpiece material along respective filamentary channels. Subsequently, the filamentary channels are widened to the desired diameter of the holes.
