　　Comparing Fiber Lasers to CO2 Lasers

　　

　　Previously used for metal plate cutting (8 ~ 20mm) laser mainly CO2 laser-based. CO2 laser generator size, occupies a large space. It is difficult to realize multi-gun cutting because of the high requirements for the frame and guide rail. The optical path relies entirely on copper mirrors to propagate. Optical path attenuation fast optical path requirements, energy loss is more. CO2 laser source through the CO2-based gas mixture by the high-pressure excitation to produce laser. Therefore, the photoelectric conversion rate is low, only 10%, so the operating cost is high.

　　

　　For fiber laser, because all the collision excitation between molecules occur in the fiber. The pump source consists of one or more high-power semiconductor arrays coupled together, so the energy required is greatly reduced. It is about one-third that of CO2 lasers. As less heat generation occurs, the size of the cooler reduces accordingly. In short, in the case of achieving the same performance, the overall energy consumption of fiber lasers than CO2 lasers 70% lower. With the continuous development of high-power fiber laser, alternative CO2 laser cutting metal plate material has become a reality.

　　

　　Advantages of Fiber Laser Energy

　　

　　Fiber lasers use multiple multimode pump diodes set up in parallel as the laser source. The generated laser light passes through the branch in the adjusted coupling into a single fiber with a higher success rate. The wavelength of the fiber laser is 1.07μm, which absorbed by the fiber core after pumping and reflecting several times. And then coupled in the resonant cavity and enhanced. And then coupled in the resonant cavity and enhanced. Photoelectric conversion rate of up to 25% or more, so the fiber laser in the work of only a simple air-cooled or water-cooled heat sink.

　　

　　Fiber laser cutting equipment is the semiconductor laser light source through the fiber as the conduction medium transmission to the laser beam shaping cutting head. The laser beam then passes through the collimation system to perform collimation. With its unique multi-mode or single-mode beam through the focusing mirror in the role of the auxiliary gas for CNC cutting processing of a complete set of equipment. Fiber laser cutting machine with its high energy conversion efficiency, good beam quality, maintenance and simple cost-effective and other unique performance advantages. In recent years, it has been widely used in the sheet metal processing industry.
