  • Multiple laser beam processing
    Patent number: 11780027
    Abstract: Described herein is a system for processing a workpiece that includes a plurality of lasers that each produces a laser beam pulse. The system also includes a laser control module that sequences temporal characteristics of the laser beam pulses. Additionally, the system includes a laser beam compensation module that shapes a near field intensity profile of at least one of the laser beam pulses and adjusts a path length of at least one of the laser beam pulses. The system also includes at least one laser beam position element that combines the laser beam pulses to produce a combined laser beam pulse at a surface of the workpiece.
    Type: Grant
    Filed: March 6, 2019
    Date of Patent: October 10, 2023
    Assignee: The Boeing Company
    Inventors: Alan F. Stewart, Anthony J. Kay, Louis K. Zeldin, Andrea Koumvakalis
