Get to know MOPA Laser Marking in Metal Marking Process

The MOPA laser marking machine is very similar in design and outlook to fiber laser marking. However, the technology is internally different, and provides different capabilities. MOPA lasers provide high power efficiency using a master oscillator power amplifier approach. In this technology, MOPA produces a very coherent beam, and uses optics that can increase the strength of the beam while maintaining its main properties.

This can reach amplitudes of up to 2700 KHZ, compared to Q-switched options on fiber lasers which only go up to 500 KHZ. This machine achieves great results with reproducible multi-color marking on stainless steel, high contrast black marking on anodized aluminum, and high contrast marking on plastics.

Application

1. Since most cases on cell phones are made of anodized aluminum, the MOPA laser is used to attach high contrast IMEI and barcode numbers to the case.

2. Craft manufacturers can also come up with exquisite designs using green, pink, purple, blue, red and black colors in stainless steel.

3. Since the MOPA laser can adjust the pulse width to achieve different marking results, it will also be a good choice for plastic marking.

Advantages

1. Can mark stainless steel in various colors.

2. Less burning or melting in the surface area worked especially during engraving.

3. . Gives a more homogeneous and sometimes higher contrast mark on some plastics.

4. Reduces foam when handling plastics

Deficiency

1. MOPA technology has been around for a long time, but research is still ongoing in the field, therefore the best machines have yet to be designed.

2. MOPA machines almost always tend to be more expensive than Q-switched fiber laser markers.

3. Wood, glass, and some types of plastics will never work with a MOPA laser, as will the Q-switched pulse marker.

One of the technologies in the marking process on sheet metal is the MOPA laser. There are several advantages and disadvantages to the process of using this laser as mentioned above.
