Description
Fiber Laser Cutting Head
The Fiber Laser Cutting Head, also known as a fiber laser cutting nozzle, is a critical component of a Fiber Laser Cutting Machine. It directs the laser beam from its source to the material’s surface for cutting. This cutting head is engineered to precisely focus the laser beam into a narrow, high-intensity spot, enabling rapid and high-quality material processing.

Key Components of the Fiber Laser Cutting Head
- Collimating Lens: This lens adjusts the laser beam emitted from the fiber into a parallel beam before it enters the focusing lens.
- Focusing Lens: It concentrates the parallel beam into a small spot with high energy density, ensuring efficient material cutting.
- Nozzle: This component releases assist gas (such as nitrogen, oxygen, or air) along with the laser beam. The gas aids in expelling molten material from the cut kerf and maintains cutting quality.
- Sensor or Auto-focus System: This 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.
Characteristics of an Effective Fiber Laser Cutting Head
- High focusing accuracy.
- Compatibility with auto-focus systems.
- Support for high laser power (e.g., 1kW, 6kW, 12kW, depending on the model).
- Heat resistance and an efficient cooling system.
- Capability to operate with various assist gases.
