The wavelength of mopa laser marking machine is 1064nm, which is divided according to the wavelength of the laser. Next, Foshan Fulan Laser will talk about the main application of mopa machine.

1. Surface peeling of alumina sheet

Today's electronic products are getting thinner and lighter, and many mobile phones, tablets, and computers use thin and light alumina as the outer shell of the product. When using other types of laser marking machines to mark thin aluminum plates, it is easy to cause deformation of the material and produce a "convex hull" on the back. The use of MOPA machine marking not only is not easy to deform the material, but also more delicate shading. This is because the MOPA laser uses a small pulse width parameter to make the laser stay on the material shorter, and the energy is high enough to remove the anode layer, so for the process of stripping the anode on the surface of the thin aluminum oxide plate, MOPA Lasers are the best choice.

2. Black anodized aluminum

Use a laser marking machine to mark black trademarks, models, texts, etc. on the surface of anodized aluminum materials. This application has gradually been widely used by electronic manufacturers on the shell of electronic products in the past two years. LOGO trademark, model, etc. For such applications, currently only MOPA lasers can process them. Since the MOPA laser has a wide range of pulse width and pulse frequency adjustment, the parameters of narrow pulse width and high frequency can be used to mark the black effect on the surface of the material, and different grayscale effects can also be marked by different parameter combinations. And the marking content is smooth and has no bump.

3. Electronic, semiconductor, ITO precision marking and scribing

In precision processing such as electronics, semiconductors, and ITO, fine scribing applications are often required. Due to its own structure, the Q-switched laser cannot adjust the pulse width parameters, so it is difficult to make fine lines. Since the MOPA laser can flexibly adjust the pulse width and frequency parameters, it can not only make the scribed lines fine, but also make the edges smoother.
