MOPA laser marking machine is a marking equipment using MOPA (adjustable pulse width) fiber laser. It has good pulse shape control capability. Compared with Q-switched fiber lasers, the pulse frequency and pulse width of MOPA fiber lasers are independently controllable. Through the adjustment and matching of the 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. From this, it can be seen that the pulse width of the MOPA laser marker 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 laser marking machine.
What are the advantages of MOPA laser marking machine compared with others?
MOPA laser marking machine is suitable for fine marking process of metal and non-metal materials, such as laser engraving of digital product parts, mobile phone keys, light-transmitting keys, mobile phone shells, key panels, electronic components, oxidation, plastic marking, handicraft gifts, Oxidation treatment and coating electroplating spraying and other surface treatment.
MOPA laser marking machine is mainly used in stainless steel color marking, alumina blackening, anode stripping, coating stripping, semiconductor and electronic industry, plastic and other sensitive material marking and PVC plastic pipe industry.
However, when many customers purchase a MOPA laser marking machine, they expect its processing speed to be the same as that of an ordinary fiber laser marking machine, but this is obviously counterproductive. The two techniques are different. When engraving color effects, the machine needs to mark at high frequencies with minimal shadowing effects, which allows high resolution engraving, but at the same time the engraving speed is relatively slow.
In addition, in metal deep engraving, MOPA laser marking machine may have no advantage. Because there is no advantage in single pulse energy, but in terms of delicate effect, it is much better than ordinary laser marking machine.
Therefore, customers need to understand the advantages and disadvantages of this MOPA laser marking machine before choosing to buy one.
