What is the difference between UV laser and fiber laser?
Difference Between UV Laser and Fiber Laser
Introduction
Core Technology
- UV Laser: Utilizes ultraviolet light, typically operates at 355 nm wavelength. It's known for its precision, allowing for extremely fine marking and material processing without significant heat damage.
- Fiber Laser: Operates in the infrared range with wavelengths usually around 1060 nm to 1070 nm. It harnesses light amplified in a fiber optic cable, marked by high energy density and efficiency, suitable for cutting, welding, and marking a variety of materials.
Material Compatibility
- UV Laser: Excellently suited for plastics, glass, and certain types of metals. Its cold processing nature prevents material deformation or burning, making it ideal for delicate and heat-sensitive materials.
- Fiber Laser: Highly effective on metals and some plastics. The intense heat generated is perfect for engraving, annealing, or cutting metallic surfaces but can be damaging for very delicate or thin materials.
Applications
| Laser Type | Applications |
|---|---|
| UV Laser | Micro-machining, PCB etching, glass engraving, and marking biocompatible materials. |
| Fiber Laser | Metal engraving, automotive industry, aerospace parts processing, and electronics manufacturing. |
Advantages
- UV Laser: Exceptional accuracy and minimal thermal impact on materials. Ideal for complex, fine details.
- Fiber Laser: High efficiency and power, excellent for high-speed cutting and deep engraving. Long operational lifespan.
