MOPA Laser

MOPA is an abbreviation for “Master Oscillator Power Amplifier”, which means that the laser beam is produced by a Master Oscillator and then its power is enhanced using a power amplifier. The MOPA laser engraver uses pulses to mark or engrave different materials, which makes the MOPA fiber laser very flexible in its usage and therefore a must-have for industrial marking.

Typical use cases for the MOPA fiber laser:

1. High-contrast markings on plastics

2. Black markings on (annodized) alluminium

3. Color markings on steel

MOPA laser for laser labeling

MOPA laser for all Speedmarker laser systems.

The Trotec MOPA laser offer a higher flexibility in the adjustment of parameters due to its adjustable/variable puls duration makign it particular suitable for marking plastics and metals. MOPA lasers are available for all SpeedMarker laser marking machines.

MOPA laser offers new possibilities for marking metals and plastics.

With the MOPA laser, you can mark plastics with higher-contrast and create more legible results. Moreover, you can mark (anodized) aluminum in black or create reproducible colors on steel. In addition a MOPA laser can produce markings faster than a conventional fiber laser, while still achieving the same high quality outcome.

With the MOPA fiber laser, the pulse durations can be adjusted between 2 - 500 ns. With respect to pulse duration, the MOPA laser can simulate the properties of conventional fiber lasers (relatively long pulses) and those of classical solid state lasers (relatively short pulses) such as Nd:YAG or Nd:YVO4 (vanadate). Therefore, using a MOPA laser offers high flexibility and versatility and can accurately be adapted to fit the material marked.

Advantages of the MOPA laser.

The unique flexibility in pulse duration of the MOPA laser marking machine results in numerous advantages and new possibilities for laser marking metals and plastics:

Less burning/melting in the edge area of metal engravings
Less heat development during annealing markings on metal, which leads to a better corrosion behavior
Creation of reproducible annealing colors on stainless steel
Black marking of anodized aluminum
Controlled melting of plastics
Less foaming with plastics
More homogeneous and higher-contrast markings on some plastics

In addition, the advantages of the conventional fiber laser sources remain unchanged with a MOPA fiber laser:
