Laser source is the core part of the laser cutting machine, which determines the cutting quality and cutting efficiency. The higher the laser power, the faster the cutting speed, and the better the cutting effect. At present, there are many manufacturers in the market that have introduced different modules of lasers, and their prices are also different. Hong radium laser will give you a simple comparative analysis of the advantages.
The module composition of fiber laser is divided into single-mode and multi-mode. In the cutting application, the focus spot has a great influence on the cutting quality. The core of single-mode laser is relatively thin, the beam quality is better than multi-mode, the energy distribution is Gauss distribution, the middle energy density is the highest, and the three-dimensional diagram is a sharp and round mountain.
The core of multimode laser is coarser, the beam quality is worse than that of a single-mode laser, the energy distribution is more average than that of the single-mode laser spot, and the three-dimensional image is an inverted cup. From the perspective of the edge steepness, the multimode laser is much steeper than that of the single-mode laser.
The advantages of single-mode are thin plate, and the advantages of multi-mode are thick plate. Single-mode and multi-mode have no comparative value. They are all a configuration of fiber laser, just like a car, which is suitable for road and off-road for mountain, but the car can also run mountain and off-road can also run road. Therefore, the selection of multi-mode or single-mode fiber laser depends on the processing needs of actual end customers.
From the perspective of power level distinction, the main processing material thickness of lasers within 1000W is thin plate due to its low energy, so the single-mode configuration of lasers within 1kW is more in line with the actual situation of the market, and the lasers with more than 1kW power should be thin and thick. From the perspective of the whole processing industry, the improvement of processing quality is a rigid demand and cannot be compromised. Therefore, many high-power laser models do not consider single-mode, so the processing quality must be the first!
At the same time, the single-mode fiber core is generally thin, which means that the same power of laser transmission in it, the single-mode fiber core of the light energy bearing more, is a test of materials. At the same time, when cutting high anti materials, the combination of high-intensity reflected light and emitted laser will easily "burn the core" if the fiber material tolerance is insufficient, and it is also a challenge to the life of the core material! Therefore, many laser manufacturers still choose multimode configuration in the configuration of high-power fiber lasers!
