  • PORTABLE LASER AND DEVICE AND METHOD FOR REDUCING FOREIGN OBJECTS ON OPTICAL SURFACE
    Publication number: 20240139871
    Abstract: An apparatus or process supplies a controlled stream of gas in a laminar flow to provide a laser beam permeable barrier in a plane between laser material processing byproducts and a final laser focusing optical element to separate a contaminated environment and a clean environment without directing gas towards the processing point of the laser. The stream of gas may be directed towards a filter by a vacuum source such as a fan. The vacuum source may be sized to draw in more gas than the stream of gas.
