We often hear that the metal laser is single mode or double mode what, as the core component of the metal laser cutting machine,
the laser has a great influence on the cutting effect of the metal laser cutting machine. So in the choice of laser cutting machine,
we also need to consider the metal laser module integration way is what?
The module composition of metal laser is divided into single mode and multi-mode two,
in the cutting application, focusing spot has a great impact on the quality of cutting, single mode laser fiber core is relatively thin,
beam quality is better than multi-mode, the energy distribution is gaussian distribution,
the middle energy density is the highest, three-dimensional figure is a pointy round peak.
The fiber core of the multi-mode laser is thicker than that of the single mode, the beam quality is worse than that of the single mode,
the energy distribution is more average than that of the single mode spot, and the three-dimensional image is an inverted cup.
From the perspective of the edge steepness, the multi-mode is much steeper than the single mode.
0.9mm thin plate cutting speed single mode than multi-mode 20% higher visual effect, but from 19mm,
the speed advantage gradually decreased, from 3mm, whether it is speed or effect,
high power multi-mode laser speed and effect advantage is very obvious.
