    CORONA CFX SERIES: Programmable Beam Shape Laser

    nLIGHT’s Corona high power fiber lasers with advanced metal processing technology feature programmable beam quality enabled by groundbreaking all-fiber technology. Rapid tuning of the laser spot size optimizes machine tool performance across all metals and thicknesses.​​Users can switch from small spot size beams for maximum optical intensity—ideal for cutting thin material and for processing with nitrogen—to large donut-shaped beams used for cutting thick material with CO2-like edge quality.​​

    Key Features

    • 3 to 20 kW
    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 from 100µm to 300µm and beam shapes from top-hat to donut mode.
    Rapid Beam Switching
    Beam adjustments in less than 30ms 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
    Removal of free-space optics, zoom process heads, and external fiber-to-fiber couplers avoids complex performance-limiting hardware.
    Unparalleled Serviceability
    Modular design simplifies repairs and maximizes uptime.
