What is the MOPA laser?

Firstly, application of alumina sheet surface peeling.

Today’s electronic products are getting thinner and lighter, and many mobile phones, tablets, and computers use thin aluminum oxide as the outer shell of the product.

When Q-switched laser could mark the conductive position on a thin aluminum plate, the material is easily deform.

A “convex hull” appear on the back, which directly affects the appearance of the appearance.

The smaller pulse width parameters of the MOPA laser can make the material difficult to deform,

and the texture is more delicate and brighter.

This is because the MOPA laser uses a small pulse width parameter to make the laser stay in the material shorter,

and it has enough energy to remove the anode layer.

Therefore, for the process of stripping the anode on the surface of a thin aluminum oxide plate,

MOPA  laser is a better choice.

Secondly,Anodized aluminum black application uses laser to mark black trademark, model, text, etc. on the surface of anodized aluminum material.

This application could use to electronics manufacturers such as Apple, Huawei, ZTE, Lenovo, Meizu, etc.

in the past two years,

It could used on the shell of electronic products to mark the black mark, model, etc.

For these applications, only MOPA lasers can process them.

Because the MOPA laser has a wide range of pulse width and pulse frequency adjustment,

the parameters of narrow pulse width and high frequency could mark the effect of black on the surface of the material,

And different gray levels can be marked by different parameter combinations.
