Mopa Fiber Laser Marking Machine:

In recent years, the domestic fiber laser marking technology has been developing rapidly. Widely-used in electronic 3C products, machinery, food, packaging ect. Compared to the traditional marking technology or printing technology, it not only reduce the use of materials, but also mark well. In order to get a more beautiful mark and have more efficient processing. People are looking for different lasers for comparison. 

Here are two types of plus fiber laser , Q-switched technology and MOPA technology are often applied on the market currently. Q-switched lasers were introduced into China earlier in the year, so it is earn a large processing market share. But MOPA lasers are gradually developed in recent years, as new technology, there must be some differences between MOPA lasers and Q-switched lasers .Does it have any new technology and advantages? In the following articles, we will talk about this.


The difference between MOPA Laser and Q-switched in Marking


1) Application of Alumina Sheet Surface Stripping

The electronic products like mobile phones, computers are used thin aluminum oxide as a product shell. When using Q-switched laser mark on the thin aluminum, it easily leads the material deformation and leave "convex package" on the back, it directly impact on the appearance’s aesthetics.

While using MOPA laser, with the smaller pulse width parameters, which can keep material in a good condition. The shading is more delicate and white. This is because the MOPA laser uses a small pulse width parameter to allow the laser to stay in the material at a shorter time, and there is enough energy to remove the anode layer. So for stripping thin aluminum oxide sheet .MOPA laser is a better choice. 

2) Anodized aluminum application

Laser application has been used widely in electrical products. Such as, Apple, Huawei, ZTE, Lenovo, Meizu and other electronics manufacturers. They need to make black mark, trademark, model on the product surface. For such applications, only MOPA lasers are currently available for processing. As the MOPA laser has a wide range of pulse width and pulse frequency adjustment range. With narrow pulse width and high frequency parameters it can be marked black effect on the material surface. It can also play a different gray scale effect by adjusting the combinations of parameters.

3) Applications in electronics, semiconductors, ITO precision machining

In electronic, semiconductor and ITO laser etching precision machining, we need to elaborate line applications. For the structures of Q-switched lasers, it cannot adjust the pulse width parameters, so it is difficult to make a fine line. While the MOPA laser can flexibly adjust the pulse width, frequency parameters. So the lines were not only elaborate, but the edge appears smooth.
