What is the full meaning of MOPA?

MOPA is an acronym for Master Oscillator Power Amplifier. This refers to a two-stage laser design where a low-power seed laser (the oscillator) is followed by an amplifier that boosts its power while maintaining pulse characteristics. This architecture gives MOPA lasers their unique advantage: the ability to control pulse width and frequency independently. This means better marking quality on a wider range of materials. In the world of industrial laser marking, MOPA is synonymous with precision, control, and versatility.
