1. The laser generator is different：
Carbon dioxide laser cutting machine is a gas molecular laser that uses carbon dioxide as a medium to transmit a beam of light through a reflector. The fiber laser cutting machine is transmitted through a diode and a fiber optic cable. Multiple diodes are pumped to generate a laser beam, which is then transmitted to the laser cutting head through a flexible fiber optic cable. In carbon dioxide laser technology, the reflector must act at a certain distance, and the fiber laser cutting machine will not be subject to such restrictions.
2. Conversion rate：
Fiber laser cutting machine is currently an advanced laser technology. The solid-state laser generator it uses is more efficient than traditional carbon dioxide lasers. The photoelectric conversion rate of carbon dioxide laser cutting machine is only 8%-10%, while the photoelectric conversion rate of fiber laser cutting machine can be as high as 30%, which means that the overall energy consumption of fiber laser cutting machine is 3-5 times lower than that of carbon dioxide laser cutting machine , which improves energy efficiency by at least 86%, which is very power-saving.

3. Cutting capacity：
Fiber lasers have the characteristics of short wavelengths, thereby improving the absorption of the beam by the cutting material, and are more suitable for conduction in soft optical fibers. They are more flexible and easier to maintain than carbon dioxide lasers conducted by specular reflection. A 3KW fiber laser cutting machine is equivalent to a 4-5KW carbon dioxide laser cutting machine in terms of cutting capacity and speed, which greatly reduces operating costs.
4. maintenance costs：
The structure of carbon dioxide lasers is relatively complex, and the maintenance costs in the later stage are relatively high. The carbon dioxide gas laser system must be cleaned and maintained regularly, and the mirrors must be cleaned and calibrated regularly. Moreover, due to the purity of carbon dioxide gas, the resonator must also be maintained regularly. In addition, the turbines that deliver laser gas also have to be maintained and refurbished regularly, so the maintenance costs in the later stage are very high and complicated. The fiber laser cutting machine is more convenient and environmentally friendly in the later maintenance.
With the development of fiber laser cutting machines and their own various advantages, they have gradually replaced the market of carbon dioxide laser cutting machines. At present, carbon dioxide is mainly used for cutting non-metallic materials, such as fabrics, leather, acrylic, plastics, etc.It is also with the development of high-power fiber lasers that they are gradually occupying the processing market of thick plates.
