Fiber laser marking machines are well known to many people and are mainly used to mark various metal materials. However, few people know that metal materials can also be marked and engraved with MOPA laser marking machines. Our common mobile phone shells are usually made of alumina, and the LOGO on the surface is usually marked by a MOPA marking machine.

What is MOPA laser marking machine?

MOPA laser marking machine is a marking equipment using MOPA (adjustable pulse width) fiber laser. It has good pulse shape control ability. Compared with Q-switched fiber laser, the biggest feature of MOPA fiber laser is the output laser pulse. The pulse width is adjustable. Through the adjustment and matching of two laser parameters, a constant high peak power output and a wider range of materials can be achieved.

The pulse width of MOPA laser marking machine M1 is 4-200ns, and the pulse width of M6 is 2-200ns. The pulse width of the ordinary fiber laser marking machine is 118-126ns. From this, it can be seen that the pulse width of the MOPA laser marking machine can be adjusted in a wider range, so it is understood why some products cannot be marked by ordinary fiber laser marking machines. The effect can be achieved by using MOPA's laser marking machine.

The main application of MOPA laser marking machine?

Applicable industries of MOPA laser marking machine: mobile phone shell, IPAD, mobile phone buttons, electronic components, integrated circuits (IC), electrical appliances, communication products, sanitary ware, tool accessories, knives, glasses and clocks, jewelry, auto parts, luggage Decorative buttons, cooking utensils, stainless steel products, handicraft gifts and other industries.

The main process of MOPA laser marking machine is used for fine marking of metal and non-metallic materials, stainless steel color marking, aluminum oxide blackening, stripping anode, stripping coating, semiconductor and electronic industry, plastic and other sensitive materials marking and PVC plastic Pipe industry. It is suitable for aluminum oxide blackening, 304 stainless steel coloring, black plastic whitening, white plastic blackening and other fields, and surface treatment such as coating, electroplating and spraying.

Comparison of the effect of MOPA laser marking machine and ordinary optical fiber marking machine?

1. Marking speed difference When the MOPA marking machine engraves color effects, the machine needs to mark with the smallest shadow effect at high frequency, which makes the engraving resolution high, but at the same time the engraving speed is relatively slow.

2. For deep metal engraving, MOPA laser marking machine has shallow marking due to single pulse energy

3. The effect is beautiful, MOPA laser marking machine has better effect and more delicate
