Advantages of Fiber Lasers

1. Characteristics of Fiber Laser Technology

• Wavelength and Absorption: Fiber laser sources produce a short wavelength of 1070nm, which is a tenth of a CO2 laser’s wavelength. This property makes it more readily absorbed by metallic materials.

• Beam Quality and Processing Speed: The fiber laser beam is of high quality, which enables it to attain a smaller spot diameter. Even at longer working distances and deeper focal depths, it maintains a swift processing speed.

• Photoelectric Conversion Efficiency:

  Photoelectric Conversion Efficiency Rate	Up to 30%

• Durability and Cost Efficiency: The fiber laser source boasts an impressive lifespan of up to 100,000 hours. Its low maintenance costs and efficient fiber cable transmission, combined with its lack of dimming, make it a preferred choice over CO2 lasers, especially in metal plate cutting and welding.

• Compactness and Flexibility: The fiber laser source is compact, lightweight, and designed to be seamlessly integrated into motion systems.

• Adjustability for Diverse Applications: The spot size of the fiber laser source can be adjusted according to the specific application requirement. For instance, laser cutting demands a smaller spot for a high-quality beam, while metal welding and cladding necessitate a larger spot. This versatility explains why fiber lasers are prevalent across various sectors like laser cutting, marking, welding, cleaning, cladding, and other potential future applications.
