Understanding source, chiller and cut-head architecture makes kW and bed-size decisions clearer on the shop floor. Compare Vector platforms on the fibre laser hub, use the power guide for everyday sheet work, and the ROI calculator before you talk spec with our engineers.
The Unmatched Advantages of Fiber Laser Technology
Laser Welding: Ideal for joining dissimilar metals, thin materials, and applications demanding high weld quality and minimal distortion. Used in battery manufacturing, medical device assembly, and precision engineering.
Laser Marking & Engraving: Creating permanent markings, barcodes, serial numbers, and decorative engravings on a wide range of materials (metals, plastics, ceramics). Used for traceability, branding, and product personalization in industries like electronics, medical devices, and consumer goods.
Laser Cleaning: Precisely removing rust, paint, coatings, and contaminants from surfaces without damaging the base material. Applications include surface preparation for welding, mold cleaning, and heritage restoration.
Applications Across Industries: Where Fiber Lasers Excel
Power Level: Determine the appropriate laser power based on material thickness, processing speed requirements, and desired throughput. Higher power lasers are generally needed for thicker materials and faster processing.
Beam Delivery System: Consider the best beam delivery option for your application – fiber optic cable for flexibility, or direct beam delivery for certain high-power applications.
System Integration: Evaluate how easily the fiber laser system can be integrated into your existing production line or robotic setup.
- The Seed Laser: The journey begins with a seed laser, a low-power laser that generates the initial beam.
- Stimulated Emission: The energized rare-earth elements release photons, amplifying the laser beam’s intensity. This process of stimulated emission occurs repeatedly along the length of the fiber.
- High Efficiency: The fiber design and direct diode pumping contribute to significantly higher electrical-to-optical efficiency compared to other laser types, reducing operating costs.
