MOPA laser marking machines achieve precise marking on material surfaces through adjustable pulse width and ultra-high repetition frequency. Their biggest advantage is the ability to produce color effects while minimizing heat-affected zones, preventing material deformation or melting. The equipment typically has a power consumption of 20-100W, a compact size, and uses EZCAD or LightBurn software, making it suitable for high-end industrial precision machining.

Difference between MOPA laser marking machine and fiber laser marking machine：

Aspect	MOPA laser marking machine	Ordinary fiber laser marking machine
Laser source type	MOPA (Master Oscillator Power Amplifier, Adjustable Pulse)	Q-switched fiber (fixed pulse)
Pulse width adjustment	Adjustable (2-200ns), allowing for flexible control of the thermal effect.	Fixed (100-200ns), narrow adjustment range
Frequency range	1.6-1000kHz, high-frequency precision	20-80kHz, basically continuous or low frequency
Marking effect	Colored, multi-layered (e.g., metallic black/gold/red), with fine, light markings.	Primarily black and white/grayscale, darker colors produce better results but have limited color options.
Thermal effect	Low (suitable for plastics/thin materials, no melting/bubbling)	Medium (prone to hot spots/deformation)
Applicable materials	Metals, non-metals, plastics, glass (fine/colored)	Predominantly metal, with simple markings
Machining accuracy	Height (±0.01mm), beam quality M²<1.1	Medium (±0.05mm), beam quality M²<1.3
Power range	20-100W (Precision type)	20-500W (Industrial Type)
Price	Higher	Lower
Applicable Scenarios	Fine craftsmanship, color marking, medical/electronic	Mass production of black and white markings, industrial parts
Shortcoming	High cost	Limited color options, large heat-affected zone
