Comparative analysis of CO2 laser, YAG solid-state laser and fiber laser


Laser of cutting machines are now mainly divided into CO2 lasers, YAG solid-state lasers and fiber laser . These three types of laser cutting machines have their own characteristics in production. Below, let’s compare and analyze the characteristics and advantages of the following three lasers.

1.Operation requirements and protection

CO2 lasers need to adjust the optical path before use. The condition of the optical path will directly affect the cutting effect of the workpiece. Therefore, the optical path needs to be manually adjusted and protected regularly; the YAG solid-state laser has a significant thermal lens effect and needs frequent protection; fiber laser fiber transmission, No conditioning, no protection, high stability, simple operation.


2.Cutting speed and effect

The cutting speed of the fiber laser is 2-3 times that of the CO2 laser with equal power. The advantage is particularly outstanding in the cutting process of the metal sheet. It is very reflected in the other two laser cutting and booting. The cutting quality is good and the gap is small. , regular margin.


3. Material applicability and occupation

CO2 lasers are more widely applicable to materials, and fiber lasers are more suitable for metal materials including aluminum, copper and other high-reflective materials, which are more suitable for the processing requirements of sheet metal manufacturing, 3C household appliances and new energy industries.

4. Energy consumption level and summary cost

The photoelectric conversion rate of fiber laser is over 30%, the photoelectric conversion rate of the same power CO2 laser is about 10%~15%, and the photoelectric conversion rate of solid laser is 3%. The power consumption of fiber laser is only 20-30% of the same power CO2 laser, which is lower in sum.

Through comparison, it can be seen that the fiber laser cutting machine has higher working efficiency under equal conditions, better cutting effect, and no protection, but the purchase cost is slightly higher. Large and medium-sized enterprises can give priority to fiber optic equipment.
