摘要： An apparatus for drying a surface of a substrate (50) during laser scoring. During the laser scoring process, a narrow cooling liquid jet (100) follows the laser beam (200) 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 (300) with at least one interior chamber (310) in communication with at least one nozzle orifice (320). 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 (110) of gas that is used to clean the cooling fluid therefrom the surface of the substrate

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： 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 is configured to receive output from the laser and focus the output into an elongated laser beam having a beam waist and an extended focal depth (116) 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 receives the output from the laser, expands the output from the laser to an expanded laser beam, and transmits the expanded laser beam to the optical head.

摘要： Experimental data is presented which shows that laser scoring of glass sheets (112) with existing techniques produces unacceptable levels of residual stress in the separated sheets as the scoring speed is increased. Methods for solving this problem are disclosed which employ elongated and, preferably, asymmetrically-truncated laser beams (13). The methods allow glass sheets (112) to be scored at speeds of 1000mm/s and above with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 500 psi. 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 of the separated edges. The methods can be used with glasses of various types including glasses having low coefficients of thermal expansion.

摘要： A method and an apparatus for both scoring and separating a brittle material, and in particular a glass sheet or substrate, using only a single laser beam. A radiation zone created by the beam incident on the glass substrate, and the radiation zone is effectively formed into two portions by a coolant jet incident on the radiation zone. The radiation zone is separated into a leading portion, which generates a vent crack partially through a thickness of the substrate, and a trailing portion that propagates the vent crack through the remainder of the substrate, thereby separating the substrate.

摘要： A method is provided for separating or dividing strengthened glass articles, particularly strengthened glass sheets, into at least two pieces, one of which has a predetermined shape and/or dimension. A flaw is initiated in the glass at a depth that is greater than the depth of the strengthened surface layer of the glass, and a vent extending from the flaw is created at a vent depth that is greater than the depth of and outside the strengthened surface layer to at least partially separate the glass. In one embodiment, the vent is generated by treating the glass with a laser to heat the glass to a temperature in a range from about 50°C below the strain point of the glass up to a temperature between the strain point and the anneal point of the glass. A glass article having at least one strengthened surface and at least one edge having an average edge strength of at least 200 MPa is also described.

摘要： Disclosed are systems and methods for separating a sheet of glass by directing a microwave beam and a laser beam at a sheet of glass to propagate a crack across the sheet. A laser beam spot formed on the glass sheet by the laser at least partially overlaps a microwave beam spot produced on the sheet by the microwave beam and can be used to generate an increased power density in the overlap region, thereby forming a preferential direction for crack propagation.
