nLIGHT 12kW High-Power
Corona Fiber Lasers

The all-new nLIGHT® Corona CFX-12000 the first high power fiber lasers on the market that give users the ability to tune the beam profiles in the fiber based on their application.

With a single Corona fiber laser, users can rapidly select from high-intensity, small-spot-size beams to large, donut-shaped beams, and everything in between. This dramatic advance enables optimal thick and thin metal cutting, higher cutting speed, superior edge quality, and improved piercing time with a single tool.

End users get the best of all worlds—the speed of high-power fiber lasers for thin sheet, the quality of CO2 lasers for thick mild steel, and the high uptime and lower operating costs of a fiber laser solution.
  • 12kW
    Delivers excellent productivity for advanced cutting and welding applications

  • Optimized Tuning of Beam Size and Shape
    Maintains fiber laser performance, stability, efficiency, and reliability with spot sizes and beam shapes from small top-hat to large donut mode

  • Rapid Beam Switching
    Beam adjustments in less than 30 ms allows for real-time optimization of each process step while maintaining full-power operation

  • Back-Reflection Protection
    Hardware-based back-reflection protection allows processing of even the most reflective metals with no interruptions or damage to the laser

  • Innovative All-Fiber Beam Shaping
    All-fiber technology does not use complex, performance limiting hardware such as; free-space optics, zoom process heads, and external fiber-to-fiber couplers

  • Unparalleled Serviceability
    Modular design simplifies repairs maximizing uptime
