  • Method and apparatus for laser drilling holes with Gaussian pulses
    Patent number: 8866043
    Abstract: 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.
    Type: Grant
    Filed: July 2, 2012
    Date of Patent: October 21, 2014
    Assignee: Electro Scientific Industries, Inc.

  • Apparatus and method for non-contact sensing of transparent articles
    Patent number: 8706288
    Abstract: 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.

  • METHOD AND APPARATUS FOR HYBRID RESOLUTION FEEDBACK OF A MOTION STAGE
    Publication number: 20100301028
    Abstract: A method and apparatus is presented for obtaining high resolution positional feedback from motion stages 52 in indexing systems 10 without incurring the costs associated with providing high resolution positional feedback from the entire range of motion by combining low resolution/low cost feedback devices 72 with high resolution/high cost feedback devices 74, 76, 78, 80, 82, 84, 86, 88.
