Principle and Application of MOPA Laser Marking Machine

Views:0     Author:hu     Publish Time: 2021-08-22      Origin:dapeng

Fiber laser marking machines are well known by many people and are mainly used for marking various metal materials. However, few people understand that metal materials can also be marked and engraved with MOPA laser marking machines. Our common mobile phone shells are usually alumina materials, 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 that uses MOPA (adjustable pulse width) fiber lasers. It has good pulse shape control capabilities. Compared with Q-switched fiber lasers, the biggest feature of MOPA fiber lasers is the output of laser pulses. The pulse width is adjustable. By adjusting and matching two laser parameters, a constant high peak power output can be achieved and it can be applied to a wider range of materials.


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. It can be seen that the pulse width of the MOPA laser marking machine can be adjusted in a wider range, so it is also understood why some products cannot be printed by the ordinary fiber laser marking machine The effect can be achieved by using MOPA laser marking machine.

The main application of MOPA laser marking machine?

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


The main process of MOPA laser marking machine is used for fine marking of metal and non-metal materials, stainless steel color marking, aluminum oxide blacking, anode stripping, coating stripping, semiconductor and electronic industries, plastics and other sensitive materials marking and PVC plastics Pipe industry. It is suitable for the fields of aluminum oxide blackening, 304 stainless steel coloring, black plastic whitening, white plastic blackening, etc., coating, electroplating, spraying and other surface treatments. The laser pattern fonts are environmentally friendly and meet the ROHS standard.

What is the comparison between MOPA laser marking machine and ordinary fiber marking machine?

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


2. Metal deep engraving, MOPA laser marking machine has a shallower marking due to single pulse energy


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