摘要： A substrate (1) having a first groove (4) is provided with a protrusion (3) on the first groove (4). This protrusion (4) preferably has a top with an apex angle of 30 to 150 degrees and results in a controlled breaking of the substrate (1) and a minimum of loss due to deviations of the crack initiated at the protrusion (4).

摘要： A U-shaped groove is formed in a glass sheet along a cutting line and the sheet is cut by breaking along the groove. The groove is formed by heating a sheet portion including the cutting line by a laser beam, cooling it to lower its density, and etching that portion to dissolve it. Every surface exposed by cutting the sheet has a pair of edges which are properly beveled and rounded.

摘要： A method of laser processing or laser modification of materials. The combination of ultrafast laser pulses and high-repetition rate (>100 kHz) bursts (or continuous operation) defines a new and unexpected regime for material processing. The high repetition rate controls thermal and/or other relaxation processes evolving between each ultrafast laser pulse that ‘prepares’ the sample surface or bulk to alter the interaction with subsequent ultrafast laser pulses and thereby improve or optimize the process, or enable a new process, that are not available at lower repetition rate. The addition of this laser-controlled thermal component, and/or the general control of relaxation processes, overcomes several current limitations of ultrafast laser processing at lower repetition rates (

摘要： Flat membranes from foils of organic polymers, glass or ceramic materials have pores tapering in funnel-shaped fashion, with a fixed pore size and a pore size distribution of less than 10% and an arrangement of the pores in a pattern of adjacent rows, wherein the average pore diameters range from 0.05 to 10 .mu.m and the pore patterns are evenly arranged in a regularly bounded area and, between the individual pores, have remaining webs with varying heights in the plane parallel to the increase in thickness of the foil material. It is manufactured through erosion of the pores by use of one or more intensity-modulated laser beams and continuous transport of the foil past the laser or lasers, with a pulse duration ranging from 1 to 1000 ns.

摘要： In a method for manufacturing a glass plate that includes chamfering processing for chamfering an edge surface of a glass plate, the chamfering processing includes a step of forming a chamfered surface by irradiating the edge surface of the glass plate with a laser beam, and a step of heating the glass plate before the chamfered surface is formed. When a temperature of the glass blank at which the glass blank is heated is Tp [° C.], a glass transition point of the glass blank is Tg [° C.], and an average coefficient of linear thermal expansion of the glass blank is α [1/° C.], (Tg−Tp)≤−5.67×107·α+840 is satisfied.

摘要： Methods of laser processing a transparent material are disclosed. The method may include positioning the transparent material on a carrier and transmitting a laser beam through the transparent material, where the laser beam may be incident on a side of the transparent material opposite the carrier. The transparent material may be substantially transparent to the laser beam and the carrier may include a support base and a laser disruption element. The laser disruption element may disrupt the laser beam transmitted through the transparent material such that the laser beam may not have sufficient intensity below the laser disruption element to damage the support base.

摘要： A method produces a structured element by material-removing machining of a workpiece with pulsed laser radiation, the workpiece consisting of a workpiece material transparent to the laser radiation, the laser radiation being radiated into the workpiece from a radiation entry side and, in an area of a rear side of the workpiece located opposite the radiation entry side, being focused within the workpiece in a focus area such that workpiece material is removed in the focus area by multi-photon absorption, and includes bringing the rear side of the workpiece, at least in a machining area currently being machined around the focus area, into contact with a free-flowing liquid transparent to the laser radiation, wherein at least some of the liquid is set to flow in a direction towards the machining area such that the liquid flows into the machining area at an acute angle of 60° or less to the rear side.
