📝 Editor's Review
6kW beam source with multi-stage back reflection immunity for processing highly reflective metals
While Coherent provides lasers for integration, the FL6000 is a standout. It shines where other lasers fail: cutting and welding highly reflective materials. Its built-in back-reflection immunity safeguards the optics when dealing with pure copper or polished aluminum, making it an incredibly resilient engine for high-end fabrication cells.
Best For: Specialized welding and surface treatment of brass, copper, and aluminum alloys
