What is a MOPA Laser?
MOPA (Master Oscillator Power Amplifier) lasers use a DUV light source design, increasing their performance and cost-effectiveness. MOPA laser has a master oscillator that generates light from low energy while the power amplifier intensifies the light to reach the necessary laser power.
What Can I Engrave With A MOPA?
MOPA laser has a large range of pulse duration. As a result, they have a larger scope of material compatibility. The laser system can make high contrast and accuracy on materials such as
- Metals: Aluminum, stainless steel, gold, brass, titanium, carbon steel, platinum, and tungsten.
- Plastics: PC, PLA, PBT, ABS,
What Are The Advantages Of A MOPA Laser Engraving Machine?
Below are a few reasons you should consider a MOPA laser marking machine:
· Kinder to metals
MOPA lasers do not produce much heat as other laser marking machines. As a result, there is less damage to the part you are marking. Furthermore, there is a reduction in the development of rust and subsequent burning/melting of the edge area. As a result, using MOPA lasers does not compromise the product’s corrosion resistance.
· Color marking in Stainless Steel
Color marking using a laser marking machine has been possible for a long time. However, MOPA lasers are more accurate and precise in color marking, especially in stainless steel materials
· Black marking of anodized aluminum
Removing the top layer of an anodized aluminum produces a faded white mark using a conventional laser marking machine. However, MOPA lasers allow you to repaint the anodized layers using its short pulse durations.
· Increased precision when melting plastics
MOPA laser markers can produce clear markings on plastic parts without foaming or melting, as other machines do. As a result, the marking is of higher quality and more uniform.
Other advantages of using the marking system are increased longevity and low maintenance.
