What is a MOPA laser?
The term master oscillator power amplifier (MOPA) refers to a configuration consisting of a master laser (or seed laser) and an optical amplifier to boost the output power. This gives extra flexibility, e.g. when a gain-switched laser diode (→ picosecond diode lasers) is used as a seed laser.
How does MOPA laser work?
In MOPA lasers, an optical amplifier is used to create the focal point. The master oscillator produces a highly coherent beam, which is then amplified by the optical amplifier to increase the output power while preserving the main properties of the oscillator.
Can a MOPA laser deep engrave?
Engraving and deep engraving of metals. MOPA lasers open up many new possibilities for marking plastics and metals, including high-contrast marking, color on certain metals, and more. We will also share time and quality-optimized laser parameters for deep engraving of metals to help you improve your results.
What is a MOPA amplifier used for?
MOPA lasers (like Y. 0201) are optimally suited for marking naturally and colored anodized aluminum to create black markings without damaging the surface. They are also used for high-contrast marking of various other metals (e.g. nickel alloys, steels, titanium).
What is the difference between laser marking and laser engraving?
Generally speaking, Laser Marking refers to placing legible information onto the surface of a part with little or no penetration whereas Laser Engraving refers to placing information into a part with obvious penetration below the surface.
What can you engrave with a fiber laser?

What is a seed laser?
A seed laser is a laser whose output is injected into some amplifier or another laser. Seed lasers are typically combined with an amplifier in a master oscillator power amplifier configuration used for generating an output with high power.
What is MOPA fiber laser marking machine?
This MOPA fiber laser marking machine comes with top brand laser sources such as JPT, 20W, 30W, 50W are available in laser power, laser pulse and frequency are independently adjustable, suitable for all kinds of metal marking,color marking on stainless steel, alumina marking and other applications.
What is the difference between MOPA fiber laser and Q-switch laser?
Although MOPA fiber laser has many advantages,but it is much more cost than Q-switch laser, usually we just choose a common fiber laser marking machine. Only select MOPA laser marking machine when require color marking on stainless steel and black marking on anodized aluminum.
What is the pulse duration of the Mopa laser?
With the MOPA laser, the pulse durations can be set to predefined values between 4 and 200 ns. Because it offers such a wide range of pulse durations, the MOPA is one of the most flexible lasers on the market.
What is the difference between YAG and MOPA fiber lasers?
Unlike YAG lasers, MOPA fiber lasers utilize semiconductor diodes as the pumping mechanism and a doped fiber optic cable as the gain medium. For these fiber lasers, the doped fiber optic also serves as the resonator. MOPA fiber lasers are much more reliable and efficient than previous laser technologies.
