High Power CW Fiber Lasers

This is a high-power CW fiber laser-single-module, 4,000W to 6,000W output, QBH connector, air-cooled. Used as the primary source in flat-sheet cutting systems for carbon steel up to 25 mm and stainless steel up to 20 mm.

High Efficiency
Advanced pump coupling and single-mode fiber design deliver ≥45% electro-optical efficiency-more cutting power per kW of input energy.

Minimal Maintenance
Fully sealed fiber-optic architecture eliminates mirror alignment and resists dust, moisture, and contamination-ideal for 24/7 production.

EMI-Resistant Operation
Closed oscillator design + 1070nm stable emission ensures immunity to external electromagnetic noise from VFDs, welders, or RF sources.

Plug-and-Play Integration
Standard QBH output interface compatible with all major cutting/welding heads-no custom adapters needed.

Reliability
All lasers undergo 100+ hours of aging test and power stability validation before shipment-MTBF > 100,000 hours.

Is this a single-module or multi-module laser?
This is a true single-module design (not beam-combined), offering superior beam quality and easier integration than multi-module alternatives.

Can it be used for cutting copper or brass?
Yes-with proper cutting head (high anti-reflection optics) and nitrogen assist gas. We provide application notes for reflective materials upon request.

What chiller specs are required?
For 6kW: flow rate ≥ 12 L/min, temperature stability ±0.5°C, pressure 4–6 bar. We can recommend compatible chiller models.

Do you offer software for remote monitoring?

Yes-our optional LaserControl Suite allows real-time power monitoring, fault logging, and scheduled maintenance alerts via Ethernet.

How does your 6kW laser compare to IPG or Raycus?

While we respect those brands, our laser delivers comparable beam quality and wall-plug efficiency at a more competitive price-ideal for cost-sensitive OEMs without compromising reliability
