People often ask us questions like what should we choose, the Fibre laser marker or the Co2 marker?

Well, the answer to this question is not too simple and straightforward. There are also many factors to consider if you are thinking about buying or using any of these laser technologies. So before you make up your mind about investing your hard-earned money into any of these technologies, it’s better to look at the significant difference between these two.

So, let’s explore some of the major differences between the Co2 and the Fibre Laser marker:

Consumption of power:

In this world of the energy crisis, it is essential to think about the power consumption in using these technologies. When it comes to power consumption, the fibre laser marker consumes less energy. The reason for the less power consumption by the fibre laser marker is that the oscillator, as well as the chiller units, help in the reduction of power consumption. When at maximum power, the oscillator and the chiller combination in the fibre laser marker will consume a maximum of 18kW energy. On the other hand, the same combination of chiller and oscillator in a Co2 laser will consume up to 70kW of power. Thus, if you are concerned about energy saving, you can choose the fibre laser marker, as it will be more energy-efficient.


When it comes to the speed of both these technologies, the answer can’t be too simple. This is because both have a speciality in separate areas. A fibre laser can cut as much material as Co2 in the same time interval. When it comes to cutting of materials like copper, brass, and aluminium, the beams are better absorbed by the fibre laser marker. But when it comes to cutting off a steel sheet, the speed of both laser technology are almost the same. The only difference, in this case, is that the pierce time much less on fibre. For materials with thickness more than 0.5 inches, the Co2 technology has better and finer edge quality. If you want to cut a stainless steel sheet with nitrogen, the speed of the fibre is quicker, but the edge quality of the Co2 is better and finer. Thus, each of these technologies has different advantages and disadvantages, and the choice entirely depends on your use and the quality of cutting you want. 

Safety and Risk:

In the case of a Co2 laser cutting system, the operator is not directly exposed to the laser beams, but the system is not completely enclosed. People can use normal plastic enclosure and safety glasses to protect their eyes from the laser beams. When it comes to Fibre laser markers, the wavelength of the laser beam is much stronger and dangerous. Thus when you are using a Fibre laser marker, you should consider taking special measures and precautions. In terms of safety, the Fibre laser marker belongs to class I, whereas the Co2 laser marker belongs to class IV. 

Edge quality:

Another significant feature that differentiates between these technologies is the edge quality. Edge quality means the precision and smoothness by which the material is cut or engraved. In material with all thickness size, Co2 cuts with better and finer edge quality. Thus, Co2 can work well, when it comes to cutting of thick material. In addition to this, the fibre laser marker has one more disadvantage as per which it consumes more assist gas while cutting. On average, the Fiberglass marker consumes 30% more assist gas while cutting. The wavelength of fibre laser cutters is better suited for cutting thinner and reflecting materials. 


Cost is a big factor when it comes to using the Co2 laser cutting and the Fibre laser marker. The cost of Fibre laser cutting is almost half of the Co2 laser cutting. The reason for the low cost is that fibre laser cutting involves low power consumption and high electrical efficiency. In addition to this, energy is also saved by the chillers and the oscillators. When running at maximum power, the Fibre laser marker will consume a maximum of 18kW of energy. On the other hand, a Co2 laser cutter working at the same frequency and power will consume at least 70kW of electricity. 

The fibre laser marker technology is very new and still many manufacturers and industries are hesitant in using the technology. But gradually, the fibre laser marker usage will grow in momentum when people keep on using this. 

When it comes to deciding which technology is best for your usage, you need to consider all the above-mentioned factors. So, if you are considerate about power consumption, the fibre laser technology is better. But when it comes to using assist gases, the Co2 laser technology is better.
