Description
Fiber Laser Cutting Head

The Fiber Laser Cutting Head is a critical component of a Fiber Laser Cutting Machine, responsible for directing the laser beam from the source to the material surface for cutting. This head is engineered to precisely focus the laser beam to a narrow point, enabling high-quality and rapid material processing.
Key Components of the Fiber Laser Cutting Head
- Collimating Lens: Adjusts the laser beam from the fiber into a parallel beam before it enters the focusing lens.
- Focusing Lens: Concentrates the parallel beam into a small, high-energy-density spot for efficient material cutting.
- Nozzle: Discharges assist gas (e.g., Nitrogen, Oxygen, or Air) alongside the laser beam. This gas helps to clear molten material from the cut kerf and maintains cut quality.
- Sensor or Auto-focus System: Measures the real-time distance between the cutting head and the material surface and automatically adjusts the height to optimize the cutting process.
- Cooling System: Due to the high power of the laser beam, the cutting head incorporates a water or air cooling system to prevent thermal damage.
Features of an Optimal Fiber Laser Cutting Head
- High focusing accuracy.
- Compatibility with auto-focus systems.
- Support for high laser powers (e.g., 1kW, 6kW, 12kW, depending on the model).
- High thermal resistance and efficient cooling systems.
- Versatile compatibility with various assist gases.
