  • Athermalized permanent-alignment optical-element mount
    Patent number: 8785818
    Abstract: A mounting fixture for mounting an optical element on a base-plate has spaced-apart parallel legs attachable by brackets to the base-plate and a mounting platform attached to the legs. The platform can be heated by a removable heater. The optical element is held in a mounting tab attached to the platform by a solder-pad. Heating the platform softens the solder-pad allowing the tab and the element to be aligned. Removing the heat allows the pad to harden to complete the attachment and retain the alignment of the element on the mount.
    Type: Grant
    Filed: February 3, 2012
    Date of Patent: July 22, 2014
    Assignee: Coherent, Inc.

  • Beam dump for a very-high-intensity laser beam
    Patent number: 8047663
    Abstract: A beam terminator for a high-power laser beam comprises a thermally conductive body including a beam-trapping chamber. A tapered spiral channel extends into the conductive body for guiding the beam. The beam is partially absorbed while propagating along the channel to the trapping chamber. What remains of the beam is absorbed in the trapping chamber.
