Description
Fiber Laser Cutting Head

Fiber Laser Cutting Head is a critical component of Fiber Laser Cutting Machines, responsible for directing the laser beam from the source to the material surface for cutting operations. This cutting head is engineered to precisely focus the laser beam to a narrow point, enabling high-speed and high-quality material processing.
Key Components of a Fiber Laser Cutting Head
- Collimating Lens: Adjusts the laser beam emitted from the fiber to a parallel beam before it enters the focusing lens.
- Focusing Lens: Concentrates the parallel beam into a small spot with high energy density for efficient material cutting.
- Nozzle: Discharges assist gas (e.g., Nitrogen, Oxygen, or Air) along with the laser beam to help eject molten material from the cut kerf and control cutting quality.
- Sensor or Auto-focus System: Measures the real-time distance between the cutting head and the material surface, automatically adjusting the height for optimal cutting performance.
- Cooling System: Due to the high energy of the laser beam, the cutting head incorporates a water or air cooling system to prevent damage.
Features of an Optimal Fiber Laser Cutting Head
- High focusing accuracy.
- Compatibility with auto-focus systems.
- Support for high laser power (e.g., 1kW, 6kW, 12kW, model-dependent).
- Heat resistance and efficient cooling system.
- Versatility for use with various assist gases.
