MOPA laser marking machine is also called aluminum laser marking machine, color laser marking machine and so on.

The pulse frequency and pulse width of MOPA fiber laser of MOPA laser marking machine are independently controllable.Mopa laser source By adjusting and matching the two laser parameters, constant peak power output can be achieved and it can be applied to a wider range of marking substrates. Fiber mopa laser raycus It has the advantages of first pulse, wider pulse width adjustment and faster response speed.

20w mopa laser marking machine is mainly used in stainless steel color marking, alumina blackening, stripping anode, stripping coating, semiconductor and electronic industries, plastics and other sensitive materials marking and PVC plastic pipe industry.

1. anodized black application

60w mopa laser engraving machines Using laser to mark black trademarks, models and characters on the surface of anodic alumina materials, this application has gradually been widely used by Apple, Huawei, ZTE, Lenovo, Meizu and other electronics manufacturers in the last two years to Mark trademarks and models of black marks. For such applications, only MOPA lasers can be processed at present. Because the MOPA laser has a wide range of pulse width and pulse frequency adjustment range, using narrow pulse width, high frequency parameters can mark the surface of the material black effect, through different combinations of parameters can also mark the effect of different gray levels.

2. alumina sheet surface stripping

Today's electronic products are becoming thinner and thinner, and many mobile phones, tablets, and computers use light alumina as the shell of the product. When Q-switched laser is used to mark the conductive potential on thin aluminum plate, it is easy to cause material deformation and "convex hull" on the back, which directly affects the appearance of the beauty. Using the parameters of MOPA laser with smaller pulse width, the material can not be easily deformed, and the bottom lines are more delicate and white. This is because MOPA lasers use small pulse width parameters to make the laser stay in the material shorter time, and have enough high energy to clear the anode layer, so for thin alumina plate surface stripping anode processing, MOPA laser is a better choice.

3. electronic, semiconductor, ITO precision machining applications

In the precision machining of electronics, semiconductors and ITO, fine scribbling applications are often needed. Q-switched laser can not adjust the pulse width parameters because of its own structure, so it is difficult to draw fine lines. MOPA laser can flexibly adjust the pulse width and frequency parameters, not only can make the scratch line fine, but also the edge appears smooth and not rough.
