What is a MOPA Fiber Laser Marker?

Fiber laser marker machine, as one kind of laser marking system, has been widely used for permanent and high quality marking in different industries.

MOPA Fiber Laser Marker

Though many laser systems are available by now on the market, the MOPA fiber laser marker remains as one of the most innovative and technologically advanced systems you can find owing to its excellent marking performance and high cost effectiveness over other laser marking systems.

1.Meaning of MOPA laser

The term MOPA is actually an abbreviation for master oscillator power amplifier. The MOPA laser has two gas discharging chambers, namely, the master oscillator and the power amplifier.

laser beam is generated by the master oscillator with a low amount of energy in a tight spectrum, the laser beam is then passed through the the power amplifier chamber, which amplifies the beam to the necessary power levels.

The pulse frequency and pulse duration can be adjusted which provides a wider range of laser marking parameters and more marking options. With MOPA laser, plastics can be marked with with higher-contrast and more legible results, also, black marking of anodized aluminum and create reproducible color marking of steel are available, MOPA lasers are thus an important alternative for many applications due to their high flexibility.

2.Advantages of MOPA laser

Air-cooling with high ambient air temperature operating;

Efficient running with low power consumption;

Longest diode life (up to 100,000 hours)

High peak power and long pulse duration makes high-speed and deep marking possible

Less burning/melting in the edge area of metal material

Small heat affected zone during markings on metal, which leads to a better corrosion behavior

Black marking of anodized aluminum

Color marking of stainless steel

3.Applications for MOPA laser

MOPA Fiber Laser Marker application

Excellent blacking marking for anodized aluminum without damaging the surface;

A wide range of reproducible color marking on stainless steel, also, can be used for high-contrast marking of various other metals.

Can carry out marking, etching and engraving on the surface of a variety of materials, including:

Steel, SS, nickle, aluminum, alloy, titanium, brass and copper, painted materials, black oxide, polyethylene, ABS plastic, Carbide, PCD and so much more!
