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.​​

  • Advanced Metal Processing.
  • High-power fiber lasers with programmable beam technology.
  • Uninterrupted processing of thin and thick materials.​

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.​​

Features and benefits.

  • 3 to 15kW power options
  • ​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 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​
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 and​ maximizes uptime. ​​​​​
