20090308854 | AUTOMATIC RECIPE MANAGEMENT FOR LASER PROCESSING A WORK PIECE - To better address these problems, one or more characteristics are measured from a work piece ( | 12-17-2009 |
20120043306 | METHOD AND APPARATUS FOR OPTIMALLY LASER MARKING ARTICLES - The invention is a method and apparatus for laser marking a stainless steel specimen with commercially desirable marks. The method includes providing a laser processing system having a laser, laser optics and a controller with pre-determined laser pulse parameters, selecting the pre-determined laser pulse parameters associated with the desired mark, and directing the laser marking system to produce laser pulses having laser pulse parameters associated with the desired marks including temporal pulse widths greater than about 1 and less than about 1000 picoseconds. | 02-23-2012 |
20140015170 | METHOD AND APPARATUS FOR MARKING AN ARTICLE - Numerous embodiments of methods and apparatus for marking articles are disclosed. In one embodiment, a method of marking an article includes providing an article having a preliminary visual appearance; modifying a region of the article; and directing a plurality of optical pulses into the modified region of the article. The plurality of optical pulses can be configured to produce a visible mark on the article. Generally, the mark can be characterized as having a modified visual appearance different from the preliminary visual appearance. | 01-16-2014 |
20140016103 | INTERACTIVE CONTROL SYSTEM, METHODS OF MAKING THE SAME, AND DEVICES INCORPORATING THE SAME - Numerous embodiments of interactive control systems, methods of making the same, and devices incorporating the same are disclosed. In one embodiment, a system includes a light-resistant material; light-transmissive holes penetrating in a light-transmissive pattern through the light resistant material; and a lens disposed adjacent to the light-transmissive pattern. | 01-16-2014 |

20090242528 | METHOD AND APPARATUS FOR LASER DRILLING HOLES WITH GAUSSIAN PULSES - An improved method and apparatus for drilling tapered holes in workpieces with laser pulses is presented which uses defocused laser pulses to machine the holes with specified taper and surface finish while maintaining specified exit diameters and improved system throughput. A system is described which can also drill holes with the desired taper and surface finish without requiring defocused laser pulses. | 10-01-2009 |
20100298964 | APPARATUS AND METHOD FOR NON-CONTACT SENSING OF TRANSPARENT ARTICLES - A laser-based displacement detector is used to detect cosmetic coatings applied to one surface of the transparent article and thereby determine which side is uppermost when loaded into the laser processing system. In particular, articles that are transparent to visible light and are particularly difficult to orient properly in laser processing systems are oriented using a laser-based displacement detector in conjunction with a partial coating on the article. | 11-25-2010 |

20100078419 | POST-LENS STEERING OF A LASER BEAM FOR MICRO-MACHINING APPLICATIONS - In a laser micro-machining system including a simple focusing lens located between a laser source and a beam steering mechanism along the path of a laser beam pulse. The focusing lens being a simple single-element spherical lens with an optical axis of the focusing lens located inline with a laser beam input from the laser source. The focusing lens located further away from a work piece than the beam steering mechanism. An active beam path management system moves the simple focusing lens in concert with and relative to the beam steering mechanism to maintain a focal point coincident with a surface of the work piece at all deflection angles affected by the beam steering mechanism. The focusing lens is rapidly moveable in concert with the beam steering mechanism to maintain a constant beam path length from the lens output to the work piece at all times. | 04-01-2010 |
