  • Laser based machining
    Patent number: 12083620
    Abstract: A direct write laser based machining process wherein a laser beam is controlled to machine a glass material in an interlaced raster scan pattern. An embodiment of machining a glass substrate to form an optical element is described. An ultrashort pulsed laser is used for machining and smoothing fused silica, followed by CO2 laser polishing. High speed and high quality machining is possible using this approach, which allows efficient use of high laser repetition rates.
    Type: Grant
