Corona Fiber Lasers

6kW cutting speeds, 90μm


Programmable beam quality for more efficient metal processing

The CFX-5000 utilizes a unique all-fiber beam tuning capability to give end users thin sheet cutting speeds characteristic of a 6kW fiber laser, along with excellent thick metal edge quality similar to a CO2 laser, without the need to change any optics. This increase in performance allows job shops to get the productivity benefits of a 6kW with the lower costs of ownership a 5kW laser provides.

End users get the best of all worlds—the speed of high-power fiber lasers for thin metal processing, the quality of CO2 lasers for thick metal cutting, plus the high uptime and lower operating costs of a fiber laser solution. The CFX-5000 lowers the cost of ownership, increases productivity, and expands a job shop’s capability.


5kW with Cutting Speeds of a 6kW

Get all the productivity benefits of a 6kW with the lower cost of ownership of a 5kW.


Optimized Tuning of Beam Size and Shape

Maintains fiber laser performance, stability, efficiency, and reliability with spot sizes from 90um to 300um and beam shapes from top-hat to 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 to maximize productivity.

Back-Reflection Protection

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

Breakthrough Integrated Beam Shaping

All-fiber solution avoids free-space optics, zoom process heads, and external fiber-to-fiber couplers providing reliable maintenance-free operation.

Unparalleled Serviceability

Modular design simplifies repairs maximizing uptime.
