Advantages & Application of 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 pulse frequency and pulse width of MOPA fiber laser are independently controllable. Through the adjustment and matching of two laser parameters, it can achieve constant peak power output and be applicable to a wider range of materials.

The pulse width of MOPA laser marking machine M1 is 4-200ns and that of M6 is 2-200ns. The pulse width of ordinary optical fiber laser marking machine is 118-126ns, so it can be seen that the adjustable range of pulse width of MOPA laser marking machine is wider. Therefore, we can understand why some products can not produce the effect of ordinary optical fiber laser marking machine, which can be achieved by using MOPA laser marking machine.

MOPA laser marking machine is applicable to the fine marking process of metal and non-metallic materials, such as laser black marking of digital product parts, mobile phone keys, transparent keys, mobile phone outer shell, key panel, electronic components, oxidation, plastic marking, handicrafts and gifts, oxidation treatment, film plating 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, marking of plastics and other sensitive materials and PVC plastic pipe industry.

However, when purchasing MOPA laser marking machine, many customers expect its processing speed to be the same as that of ordinary optical fiber laser marking machine, but this obviously backfires. The two technologies are different. When engraving color effects, the machine needs to mark with the smallest shadow effect at high frequency, which makes the engraving resolution high, but the engraving speed is much slower at the same time.

In addition, MOPA laser marking machine may have no advantage in metal deep engraving, because it has no advantage in single pulse energy, but its effect is better than that of ordinary laser marking machine. Therefore, before choosing to buy MOPA laser marking machine, customers need to understand the advantages and disadvantages of this kind of laser marking machine.
