Fiber Laser Cutting: Everything You Need to Know

Aug. 14, 2023

Fiber laser cutting has revolutionized the field of industrial manufacturing, offering precision, speed, and versatility in cutting a wide range of materials. This advanced technology utilizes the power of focused light to achieve accurate and efficient cuts, making it an essential tool in various industries. This comprehensive guide covers the fundamental aspects of fiber laser cutting, from its working principle to its applications and benefits.

Understanding Fiber Laser Cutting

Fiber laser cutting is a process that uses a high-powered fiber laser to cut through materials with exceptional accuracy. The laser beam is generated by amplifying light through a fiber-optic cable and then directing it onto the material to be cut. This concentrated energy rapidly heats and vaporizes the material, creating a clean and precise cut. Fiber lasers are particularly effective in cutting materials such as metals, plastics, ceramics, and composites.

How Fiber Laser Cutting Works

Laser Generation: A high-powered laser source generates a laser beam by exciting a gain medium, often made of rare-earth elements like ytterbium. This creates a concentrated beam of light at a specific wavelength. 

Fiber Delivery: The laser beam is delivered through a flexible fiber-optic cable to the cutting head. This delivery method allows for easy manipulation of the beam's position and intensity. 

Focusing Optics: The laser beam passes through a series of focusing optics, which concentrate the energy into a small spot size. This focused beam has the intensity needed to cut through the material. 

Material Interaction: The focused laser beam strikes the surface of the material, rapidly heating and vaporizing a small area. The energy transfer melts or vaporizes the material, creating a cut. Assist Gas: During cutting, an assist gas (often nitrogen, oxygen, or air) is blown onto the cutting zone. The gas helps remove molten material and debris from the cut, ensuring clean edges.
