How to choose a suitable laser for the fiber laser cutter?

Fiber lasers are the core components of the fiber laser cutter and it have a large impact on the cutting performance of laser cutting machines.

When choosing a laser cutting machine, what is the module integration method that needs to consider fiber lasers?

The module composition of the fiber laser is divided into single mode and multimode.

In the cutting application, the focused spot has a great influence on the quality of the cut.

The core of the single mode laser is relatively thin, and the beam quality is better than the multimode.

Its energy distribution is Gaussian with the highest energy density in the middle, and the three-dimensional map is a sharp mountain peak.

The core of a multimode laser is coarser than a single mode.

The energy distribution is smaller than that of a single mode.

The three-dimensional image is an average of a single-mode spot.

The three-dimensional image is an inverted cup.

In terms of the steepness of the edge, the multimode is much steeper than the single mode.

1mm thin plate cutting speed of single mode laser is 20% higher than multimode laser, the visual effect is similar.

However,  starting from 2mm, the speed advantage is gradually reduce. Starting from 3mm, the speed and effect of high power multimode laser are very obvious.

Therefore, the advantage of single mode is suitable for thin plate, and the advantage of multimode is thick plate.

Therefore, we cannot compare single mode and multimode with each other.

They are all a configuration of fiber laser.

It is like a car.

The car is suitable for highway and sports car is suitable for mountain.

However, the car can also run the mountain, the sports car can also run the road.

So the choice of multi-mode or single-mode fiber laser depends on the actual end-user processing needs.
