In carbon dioxide laser cutting technology, carbon dioxide gas is the medium that generates the laser beam. Fiber lasers, however, work through diodes and fiber optic cables. Instead of transmitting the beam through a mirror, a fiber laser system generates a laser beam pumped by multiple diodes, which is then transmitted to the laser cutting head through a flexible fiber optic cable. This has many advantages, first and foremost the size of the cutting table. Unlike gas laser technology, where the mirror must be set within a certain distance, fiber laser technology has no range limit. And it is even possible to mount the fiber laser next to the plasma cutting head of the plasma cutting table, which is not an option for CO2 laser cutting technology. Also, the ability to bend the fiber makes the system more compact when compared to an equivalent power gas cutting system.

Perhaps the most important and meaningful advantage of fiber cleaving technology is its energy efficiency. With the complete solid-state digital module and single design of fiber laser, the fiber laser cutting system has higher electro-optical conversion efficiency than carbon dioxide laser cutting. For each power supply unit of the CO2 cutting system, the actual general utilization rate is about 8% to 10%. For fiber laser cutting systems, users can expect higher power efficiency, around 25% to 30%. In other words, the fiber cleaving system as a whole consumes about 3 to 5 times less energy than the CO2 cleaving system, which increases the energy efficiency to greater than 86%.

Fiber lasers have short wavelength properties that increase the absorption of the beam by the material being cut, and enable 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, allowing fiber lasers to cut thinner materials quickly and cut medium thicknesses more efficiently. When cutting materials as thick as 6mm, the cutting speed of a 1.5kW fiber laser cutting system is equivalent to that of a 3kW CO2 laser cutting system. Since the operating cost of fiber cleaving is lower than the cost of ordinary CO2 cleaving systems, this can be understood as an increase in output and a decrease in commercial costs.

There are also maintenance issues. Carbon dioxide gas laser systems require regular maintenance; mirrors require maintenance and calibration, and resonators require regular maintenance. Fiber laser cutting solutions, on the other hand, require almost no maintenance. The carbon dioxide laser cutting system requires carbon dioxide as the laser gas. Due to the purity of the carbon dioxide gas, the resonator will be polluted and needs to be cleaned regularly. For a multi-kilowatt CO2 system, this would cost at least $20,000 per year. Additionally, many CO2 cuts require high-speed axial-flow turbines to deliver the laser gas, which require maintenance and refurbishment. Finally, fiber cleaving solutions have a lower impact on the earth than CO2 cleaving systems, so less cooling is required and energy consumption is significantly lower.
