Working principle and application fields of MOPA laser marking machine

The main process application fields of MOPA laser marking machine are fine marking of metal and metal composite materials, stainless steel color marking, aluminum oxide blackening, sun stripping machine, stripping coating, semiconductor and electronic industry, plastic and other Sensitive material marking and PVC plastic pipe fittings field. It is suitable for blackening of aluminum oxide, 304 stainless steel for coloring, black plastic for whitening, white plastic for blackening and other fields. Various metal composite materials, however, few people know that metal composite materials can also be marked and engraved with MOPA laser marking machine. Our common mobile phone case is usually made of aluminum oxide, and the LOGO on the surface is usually marked by 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, MOPA fiber laser is the largest The characteristic is that the pulse width of the output laser pulse 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.

What are the main application fields of MOPA laser marking machine?

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

MOPA laser marking machine is mainly used in fine marking of metal and metal composite materials, color marking of stainless steel, blackening of aluminum oxide, sun stripping machine, coating stripping, semiconductor and electronic industries , plastic and other sensitive materials marking and PVC plastic pipe fittings. It is suitable for aluminum oxide blackening, 304 stainless steel coloring, black plastic whitening, white plastic blackening and other fields. Surface treatment such as coating, electroplating, spraying, etc., the pattern fonts produced by laser are environmentally friendly and comply with ROHS standards.

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

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

2. Metal deep 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
