摘要： Methods, systems, and apparatus consistent with the present invention use multiple beams of laser energy for thermally processing a quartz object. A first laser beam is generated. A second laser beam is generated that is characteristically different than first laser beam. More particularly, the first beam and second beam may have different wavelengths, energy levels, and/or focal characteristics (such as beam geometry, beam energy distribution profile, and/or focal lengths). The first and second laser beams are then provided to a combiner, which forms the beams into a composite beam. The composite beam is then applied to a portion of the quartz object where it thermally processes the quartz by selectively heating the portion of the quartz. The composite beam may also be adjusted by changing the characteristic differences between the first and second laser beams in order to alter how the composite beam selectively heats the quartz.

摘要： Methods, systems, and articles of manufacture consistent with the present invention determine an amount of energy required to bring a quartz workpiece to a fusion weldable condition. The fusion weldable condition is a state at which the quartz workpiece is in thermal balance while being substantially near but below a quartz sublimation point. Parameters of the quartz workpiece, such as thermal properties and dimensional data, are identified. Quantifiable parameters of a heat source (such as a laser's beam energy attributes and beam geometry) are also identified. Using these parameters, a relationship is generated representing a modeled state of thermal equilibrium for the weldable surface of the quartz workpiece. This relationship is used to determine the appropriate amount of energy to be applied to the quartz workpiece and associates a desired temperature of the workpiece with a transit time for applying the energy. Heat loss can be accounted for and adjusted as part of the determined amount of energy.

摘要： A system and method for using a laser to weld a plastic substrate material to an adjacent material, such as a synthetic carpet panel. The materials are placed in contact with oppositely directed major surfaces, so as to provide an interface therebetween. The material closest to the laser is transparent to a wavelength of the laser beam, so that the impinging laser beam can be focused at a focal region on the interface. The other material adjacent to the interface is absorbent to the wavelength, so that heating of the other material by the laser beam causes a pattern of a plurality of melt zones to be formed, each melt zone consisting of portions of each of the materials. Subsequent cooling of the melt zones causes the adjacent materials to become welded together. Additives are combined with the materials to modify their transmission and absorption characteristics with respect to visible light and laser wavelengths.

摘要： Methods, systems, and articles of manufacture consistent with the present invention use laser energy for fusion welding a first quartz object to a second quartz object. The first quartz object and second quartz object have opposing surfaces to be fusion welded together. Once placed in a configuration where the opposing surfaces are substantially near each other, one or more laser beams are applied to one of the surfaces. As the first surface is heated by the laser energy, it become reflective as it nears a desired fusion weldable condition. Once reflective, the first surface reflects the laser energy to the opposing surface where the opposing surface is then heated to the desired fusion weldable condition. As the laser beam is bounced or reflected back and forth between the opposing surfaces, the surfaces are heated in a substantially even manner to allow for molecular fusing of the first object the second object into a single quartz workpiece.

摘要： A process and a device for joining or separating various workpieces, in particular made of plastic or plastic and other materials, by means of curtain-like laser beams. To join workpieces in a particular joining area of the contact surface, a mask, made of a laser-impermeable material, is arranged between the laser source and the workpieces to be joined. The laser beam and the mask are moved relative to each other. To generate high energy density in the joining area, laser beams of at least two diode lasers are brought together, and subsequently, differing laser line lengths are generated by means of a zoom optics arrangement. Via a beam splitter, a first laser beam aligned perpendicularly to the surface of the mask, is joined by at least one secondary laser beam arranged perpendicularly to the first laser beam, and the resulting laser beam is directed onto the mask. Laser beams either of different wavelengths or of the same wavelength but of different polarisation are used. In another arrangement, several laser beams are focussed parallel to each other onto the joining area by means of a lens. The method and the device not only provide adequate energy density in spite of the output of the individual lasers being insufficient per se, but also makes possible flexible adjustment of the line length.
