The difference between fiber laser and Mopa laser marker

Many clients ask us about the difference between fiber laser and Mopa laser marker.Today we will talk about it.

What is Mopa fiber laser marking machine

if The most popular way of achieving power scalability is the “MOPA” (Master Oscillator Power Amplifier) approach. The “MO” produces a highly coherent beam, and an optical “A” is used to increase the power of the beam while preserving its main properties. The “MO” has no need to be powerful, and has no need to operate at high efficiency because the efficiency is determined mainly by the “PA”. The combination of several laser amplifiers seeded by a common “MO” is essential concept of the High Power Laser Energy Research Facility. This is mopa fiber laser marking machine.

Different between Mopa laser with Q-switched laser

If Now Q-switched fiber laser marking machine is the most popular fiber laser marking solution in market. We use mopa laser on more and more fields.

so But also it have limited on some special material, such as stainless steel, anodised aluminium, plastic etc.  however mopa laser can do it.

if Compared with Q-switched fiber laser source, Mopa laser’s can adjust pluse. so it have more wide application then Q-switched laser.
