摘要： A method of operating a laser drilling system to manufacture gravure printing plates without etching or the use of hazardous chemicals includes activating a laser drilling system, including a picosecond laser, light valves, and a mechanism adapted to rotate a gravure cylinder blank. Operation of the light valves, includes setting the light valves to block and/or allow pulses of laser energy propagating from the laser drilling system that can ablate a linear pattern of cells along a substantially entire length of the gravure cylinder blank. Drilling of cells includes targeting the laser drilling system on the gravure cylinder blank, such that ablation of materials occurs as sub-beams propagate along an optical path to the target area and impinge upon the gravure cylinder blank, wherein specific cells within the target area of the gravure cylinder blank are drilled or not drilled according to settings of the light valves.

摘要： Apparatus that homogenizes a laser beam, in applications where multiple laser pulses are used to drill holes in a work piece by projecting an image of a mask onto the work piece, scans the laser beam across the mask to achieve substantially equal laser fluence through each opening in the mask. Any non-uniform beam illumination is averaged out during the multiple pulse drilling process. One embodiment of the invention uses a mirror mounted on a motor such that the reflecting surface of the mirror is at an angle to a plane which is perpendicular to the axis of rotation of the motor. This embodiment traces a circular path on the mask. Another embodiment of the invention employs two galvo mirrors to scan the laser beam. The first galvo mirror is configured to reflect the laser beam on to the second galvo mirror and the second galvo mirror is configured to reflect the laser beam onto the mask, wherein each of the first and second galvo mirrors rotates about a rotational axis in the plane of its mirror. By mounting the galvo mirrors to have orthogonal axes of rotation, this apparatus can trace the laser beam in an arbitrary pattern across the mask.

摘要： A method and apparatus for machining a work piece with a laser beam to form a circular hole in the work piece applies the laser beam to a beam rotator which rotates the laser beam about an axis of rotation before it is applied to the work piece. In one embodiment, a laser generates a laser beam having a beam area and a beam axis within the beam area. A beam rotator rotates the laser beam about the beam axis and directs the rotating laser beam to the work piece. One beam rotator employs three reflective surfaces which invert the beam across only one axis defined in the beam cross-section. Another beam rotator employs a triangular prism which receives the laser beam at a first surface at an angle of incidence equal to the Brewster's angle for the prism, totally internally reflects the laser beam from a second surface to direct the light out of the prism through a third surface. This beam rotator also employs a rotating half wave plate to ensure that the light entering the prism is p-polarized. The rotating laser beam produced by the beam rotator may be focussed into a single focussed rotating beam or diffracted to form multiple rotating laser beams.

摘要： In one aspect the invention provides a method for laser induced breakdown of a material with a pulsed laser beam where the material is characterized by a relationship of fluence breakdown threshold (Fth) versus laser beam pulse width (T) that exhibits an abrupt, rapid, and distinct change or at least a clearly detectable and distinct change in slope at a predetermined laser pulse width value. The method comprises generating a beam of laser pulses in which each pulse has a pulse width equal to or less than the predetermined laser pulse width value. The beam is focused to a point at or beneath the surface of a material where laser induced breakdown is desired. The beam may be used in combination with a mask in the beam path. The beam or mask may be moved in the x, y, and Z directions to produce desired features. The technique can produce features smaller than the spot size and Rayleigh range due to enhanced damage threshold accuracy in the short pulse regime.

摘要： A method is provided for manufacturing a high-precision mold whereby a feature matching a desired feature design is carved into a hard mold material (41) using, for example, a diamond grinding wheel and/or a diamond turning point. Inherent imprecision and errors (49) introduced by the use of the grinding wheel/turning point are measured to determine deviations from the desired feature design. An ultrafast shortpulse laser is then activated to desirably ablate the deviations, thereby correcting the errors and conforming the feature to the desired shape. Furthermore, a thin film (1602) may be formed over the feature either prior to or after the laser ablation process, where the error measurement and laser ablation processes detects and ablates errors on the surface of the thin film, respectively. Additionally, the laser ablation process may be applied directly to, for example, an optical lens (1400) formed from an imprecise mold to remove any errors and imperfections thereon.
