摘要： Systems and methods are described for forming continuous curved laser filaments in transparent materials. The filaments are preferably curved and C-shaped. Filaments may employ other curved profiles (shapes). A burst of ultrafast laser pulses is focused such that a beam waist is formed external to the material being processed without forming an external plasma channel, while a sufficient energy density is formed within an extended region within the material to support the formation of a continuous filament, without causing optical breakdown within the material. Filaments formed according to this method may exhibit lengths in the range of 100 μm-10 mm. An aberrated optical focusing element is employed to produce an external beam waist while producing distributed focusing of the incident beam within the material. Optical monitoring of the filaments may be employed to provide feedback to facilitate active control of the process.

摘要： Methods are provided for laser processing arbitrary shapes of molded 3D thin transparent brittle parts from substrates with particular interest in substrates formed from strengthened or non-strengthened Corning Gorilla® glass (all codes). The developed laser methods can be tailored for manual separation of the parts from the panel or full laser separation by thermal stressing the desired profile. Methods can be used to form 3D surfaces with small radii of curvature. The method involves the utilization of an ultra-short pulse laser that may be optionally followed by a CO2 laser for fully automated separation.

摘要： Process for removing peripheral portions such as bead regions of a glass sheet including a step of pushing the glass sheet in the peripheral portion using a pushing mechanism such as a pushing bar, and corresponding apparatus. As a result of the use of the pushing mechanism, the engagement completion time for suction cups, if used, are reduced significantly. A process without using suction cups is enabled with enhanced yield. The increased process stability and enlarged process window are particularly advantageous for processing glass sheets having high flexibility.

摘要： A method and device for separating a substrate with a laser beam. The duration of the laser beam's effect is extremely short, so the substrate is only modified concentrically about the laser beam axis (Z) without it degrading the substrate material. While the laser beam acts upon the substrate, the substrate moves relative to a laser machining head, producing plural filament-type modifications along a separating surface to be incorporated. The laser beam is initially diverted by a transmission medium having a higher intensity dependent refractive index than air, then reaches the substrate. The non-constant pulsed laser intensity increases to a maximum over the temporal course of the single pulse, then reduces, and the refractive index changes. The laser beam focus point moves between the substrate's outer surfaces along the beam axis (Z), reaching the desired modification along the beam axis (Z) without correcting the laser machining head in the z-axis.

摘要： A method of dividing a plate member made of a brittle material includes; first, forming a minute start point flaw 16 in a first main surface of a plate member on a division-planned line; then holding the first main surface of the plate member on a pair of lines; and thereafter, for example, bringing a dividing member, which heats up a second main surface of the plate member by contact heating, into contact with the second main surface of the plate member to generate a tensile thermal stress on the first main surface and applying bending force in a thickness direction of the plate member to the second main surface of the plate member, such that a tensile stress derived from the bending force and the tensile thermal stress are combined together. In this manner, the plate member is divided along the division-planned line.
