Where is the core advantage of fiber laser instead of CO2 laser

In recent years, fiber laser cutting technology has begun to be widely used in the industry. In 2014, fiber lasers surpassed CO2 lasers to become the largest share of laser sources.

Fiber laser cutting not only provides the cutting speed and quality that CO2 laser cutting can achieve, but also significantly reduces maintenance and operation costs.

Fiber laser cutting technology has high energy efficiency. With fiber laser complete solid-state digital module and single design, fiber laser cutting system has higher electro-optical conversion efficiency than CO2 laser cutting. For each power supply unit of the CO2 cutting system, the actual general utilization rate is about 8% to 10%, while the power efficiency of the fiber laser cutting system is about 25% to 30%.

Fiber laser has the characteristics of short wavelength, so as to improve the absorption of the cutting material to the beam, and can cut such as brass and copper as well as non-conductive materials. A more concentrated beam produces a smaller focus and a deeper depth of focus, so that the fiber laser can cut thinner materials quickly and cut medium-thick materials more effectively.

The CO2 gas laser system needs regular maintenance, the mirror needs maintenance and calibration, and the resonator needs regular maintenance; while the fiber laser cutting solution hardly needs any maintenance. Compared with the CO2 cutting system, the fiber cutting solution is more compact and has less impact on the ecological environment, so less cooling is required, and energy consumption is significantly reduced.
