The most important and significant advantage of fiber-optic cutting technology should be its energy efficiency. With fiber lasers, a complete solid-state digital module, a single design, a fiber laser cutting system has higher electro-optical conversion efficiency than carbon dioxide laser cutting. For each power unit of the carbon dioxide cutting system, the actual general utilization is about 8% to 10%. For fiber laser cutting systems, users can expect higher power efficiency, about 25% to 30%. In other words, a fiber cutting system consumes about 3 to 5 times less energy overall than a carbon dioxide cutting system, resulting in an energy efficiency increase of greater than 86%.
Fiber lasers have short wavelength characteristics that enhance the absorption of the beam by the cutting material and enable the cutting of materials such as brass and copper as well as non-conductive materials. A more focused beam produces a smaller focus and a deeper depth of focus so that the fiber laser can cut thinner material faster and cut medium thickness material more efficiently. When cutting materials up to 6mm thick, the cutting speed of a 1.5kW fiber laser cutting system is equivalent to the cutting speed of a 3kW carbon dioxide laser cutting system. Because fiber cutting is less costly than conventional carbon dioxide cutting systems, this can be interpreted as an increase in output and a reduction in business costs.
