摘要： Disclosed are systems for scoring non-flat materials including non-flat glass sheets (1000). In one embodiment, a laser scoring system is described. The laser scoring system includes a laser (102) and an optical head (106). The optical head (106) is configured to receive output from the laser (102) and focus the output into an elongated laser beam having a beam waist and an extended focal depth of greater than +/−5 mm relative to the center of the beam waist with a power density sufficient for scoring a material having at least a portion within the extended focal depth. In one aspect the system can include a beam expander (104). The beam expander (104) receives the output from the laser (102), expands the output from the laser to an expanded laser beam, and transmits the expanded laser beam to the optical head (106).

摘要： Disclosed are systems and methods for scoring glass sheets. A laser beam can be generated having a substantially uniform peak energy density along at least a portion of its length. The laser beam is moved across the glass sheet to create a score line. Further, the glass sheet can be separated along the score line. In some aspects, the laser beam is bimodal and comprises approximately 60-70% TEM00 mode and approximately 30-40% TEM01* mode.

摘要： Methods of using a laser to separate a glass sheet is presented that employs an elongated and, preferably, asymmetrically-truncated laser beam. The methods allow glass sheets suitable for use in modern display applications to be separated at speeds up to about 200 mm/s with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 100 psi, and preferably less than 50 psi. Glasses with high coefficients of thermal expansion (e.g. greater than about 35×10−7/° C.) maybe separated at faster speeds. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties (geometry, strength, defect-free etc.) of the separated edges. The methods can be used with glasses of various types including glasses having high coefficients of thermal expansion and also with glass sheets of different thickness.
摘要翻译：提出了使用激光器分离玻璃板的方法，其采用细长的，优选地，非对称截断的激光束。这些方法允许适用于现代显示应用的玻璃板以高达约200mm / s的速度分离，具有低水平的残余应力，例如小于或等于100psi的残余应力水平，优选较小超过50psi。具有高热膨胀系数（例如大于约35×10 -7 /℃）的玻璃杯可能以更快的速度分离。残余应力的这种低水平在显示面板（例如，LCD面板）的制造期间以及改进的分离边缘的性质（几何形状，强度，无缺陷等）转化为低水平的变形。该方法可用于各种类型的玻璃，包括具有高热膨胀系数的玻璃以及不同厚度的玻璃板。

摘要： A method of cutting glass that prevents uncontrolled crack propagation when high background stress is present, either in the form of thermal residual stress, external mechanical stress or a combination thereof. The method includes masking an edge of the glass by blocking the beam using highly reflective or absorptive material located near the glass surface, or deposited on the surface in a form of a thin film (or highly reflective paint) to prevent uncontrolled crack initiation and propagation starting from the glass edge. The initiation of the laser scoring is located at a predetermined distance from the glass edge. Yet another aspect of the invention embodies stopping propagation of the vent at the exiting end of the score line.

摘要： An apparatus for drying a surface of a substrate during laser scoring. During the laser scoring process, a narrow cooling liquid jet follows the laser beam to create and propagate a partial vent. Precision of the scoring and overall stability of the process depend upon the accuracy of the alignment of the beam and the fluid stream. In one aspect, the apparatus has a conduit with at least one interior chamber in communication with at least one nozzle orifice. The conduit is configured to be in communication with a pressurized gas source to introduce the pressurized gas into the chamber. The pressurized gas forms a curtain of gas that is used to clean the cooling fluid therefrom the surface of the substrate.
