The Georgia Tech Optec Femtosecond laser is an OPTEC WS-Flex USP system that uses a femtosecond laser to process practically any material through ultra-short laser pulses photo-ablation. The ultra-short laser pulse is effective on polymers, metal, ceramics, glass, single crystals, and polymorphic crystals. Materials are ionized by the laser pulse and removed from the surface in a plasma cloud, leaving a clean surface at the interaction site. Contrary to typical thermal laser operations, the femtosecond laser is not as sensitive to wavelength absorption and therefore offers minimum thermal, creating a no heat-affected zone on the part.

Applications include:

    Cutting
    Milling
    Drilling
    Tube processing
    Composite material cutting
    Scribing
    Surface structuring
