single mode and multiple mode of laser source

The fiber lasers are divide into single mode and multiple mode. In the cutting application, what are the advantages of the single mode laser. And what are the differences between the single mode and the multiple mode ? Today we will be with you together to find the answer!

First,The same power laser, many enterprises can do a single mode will be able to do multiple mode. 

Why do you say that? In fact, multiple mode is a complex structure that is make up of two or more single mode. A 6000w multiple mode laser can  compose of six 1000w single mode lasers, and the same a  8000w multiple mode laser can be compose of two 4000W single mode lasers or four 2000w single mode lasers.

Second,High reliability.

The single mode laser has only one optical module and one electrical module.It has simple structure, strong stability and high reliability.The more modes, the more complex the lines, the higher the damage rate. XTLASER laser cutting machine, laser single mode maximum power is 3000w. We use multi-mode lasers with power above 3000w.To enable our machines to better serve our customers, we also recommend the use of higher power single module lasers.Because product quality is the most convincing!

Also,Convenient maintenance.

The multi-module structure is complex. And it is not easy to repair. The simpler the structure of the laser is, the easier it is to repair. For the customer, the maintenance cost can effectively reduce, and the production profit can improve.

Then,When cutting high reflective materials, the cutting effect of single mode laser is better than that of multi-mode laser.

The fiber core diameter of single mode laser is fine, the spot is thin, and the aggregation energy is high. In the cutting of high reflective materials, the first is drilling. The faster the drilling, the smaller the reverse. Namely:  improve the focusing ability, shorten the perforation time, improve the cutting stability.

And,The cutting performance of thick plate is consistent with that of multi-mode: The single mode laser can achieve this performance by beam shaping and flat-top annular light output.

Generally, laser with good beam quality has more advantages in cutting thin plates, and single-mode laser has higher beam quality.Multi-mode laser is more suitable for cutting thick plate.
