Fiber laser cutting machine cuts plates in two steps: piercing and cutting. With the development of the transportation industry, aluminum alloy and other high anti-materials are used more and more, so how to achieve fast and stable cutting of high anti-materials is the problem faced by all laser cutting machine manufacturers.

　　The most critical step to realize fast and stable cutting of high anti-reflective materials is "perforation". The faster the perforation, the smaller the effect of high anti-reverse, so the shorter the perforation time when cutting high anti-reverse materials, the better, so you need a small spot and spot at the high energy density of the laser beam.

     How to choose a laser for cutting high contrast materials

　　Compared with multi-mode laser, single-mode laser has the following advantages: fine fiber core diameter, small spot, and high gathered energy, which is the best choice for cutting high anti-reflective materials:

　　1：Single-mode lasers have finer fiber core and better beam quality than multi-mode lasers.

　　2：Single-mode lasers are highly reliable, while multi-mode lasers have more complex lines and higher damage rates.

　　3：Single-mode laser is easier to maintain

　　4：Smaller size and more power saving

　　Can do multi-mode laser manufacturers may not be able to do single-mode laser, so in the cutting of high-reverberation materials, the priority choice is still a single-mode continuous laser.
