Product Introduction of MOPA Laser Marking Machine 20W 30W 50W 60W 100W
What is a MOPA Laser?
The light of marking lasers is generated in pulses. Generally, the pulse duration is non-adjustable.
What is special about a MOPA laser is that its pulse duration is variable: Long or short pulses can be adjusted.
Take an example, the stainless steel material can change the color of the surface layer of the material by adjusting the pulse width,so as to obtain a decorative effect with different colors.
MOPA laser marking machine can do black and white marking on most metals and plastics,black marking on anodized aluminum, color marking on stainless steel and titanium.
Advantages of MOPA laser For short pulses and lower pulse energy, the material is heated less and the area of the heat affected zone is reduced.
This results in more advantages and possibilities for laser marking metals and plastics.

Application Examples of Hispeed MOPA Laser Marking Machine System
1.Colorful Marking on Stainless Steel
The principle of laser engraving color development:
- Generate colored oxides;
- Generate colorless transparent oxide film, generate interference, and show color;
- Generate colored oxide and colorless oxide film at the same time.
Laser Type:Hispeed laser machine with JPT laser source
- theta lens: F=254mm
Parameters Setting:
| Color | Pulse Width | Frequency | Hatch | Speed | Power |
| Purple | 2ns | 400KHz | 0.001 | 1000 | 55% |
| Blue | 4ns | 200KHz | 0.002 | 2000 | 80% |
| Green | 13ns | 500KHz | 0.001 | 1500 | 40% |
| Yellow | 13ns | 400KHz | 0.002 | 2600 | 80% |
| Cyan | 13ns | 350KHz | 0.001 | 1500 | 40% |
Process Analysis:
Under dense hatching line space, small and medium pulse widths, and high frequency, color development is mainly affected by frequency and power.The differences in these colors are mainly affected by the laser’s single pulse energy and its spot overlap on the material.
2.Black Marking on Stainless Steel:
Marking with mid-pulse width and high frequency will not damage the surface protective layer and has no touch feeling.
Process parameters:
Laser type:Hispeed laser machine with JPT laser source
theta Lens: F=254mm,330mm
Laser Power：30-50%
Hatch Line Distance：0.01mm
Pulse width：30-100ns
Frequency：200KHz
Speed：100mm/s
Process Analysis:
Blackening of stainless steel is mainly to produce black oxides.
The JPT MOPA laser sources have a more pure black effect under large field lens
and high frequency, which is not easy to wipe off.
3.Black Marking on White Plastic
Laser type: Hispeed laser machine with JPT laser source
F-theta Lens: F=163mm, 210mm
Power：40-70%
Hatch Type:
Hatch Line Distance：0.025-0.04mm
Pulse width：60-100ns
Frequency：15-30KHz
Speed：800-1200mm/s
4.Marking barcode and data matric on PCB board
Compared with traditional sticking or printing,
Barcode or Two-dimensional codes marked by Hispeed Laser are more clear and difficult to reomve.
Bar codes can be automatically generated when marking, and code jumps automatically. It is suitable for marking of assembly line products with high efficiency.
Process parameters:
Laser type：Hispeed laser machine
F-theta lens：F＝210mm
Hatch mode：
Power：50-70%，
Hatch line space：0.02-0.04mm
Pulse width：6-30ns
Frequency：30-80KHz
Speed：1500-2500mm/s
Process analysis:
The surface material of the PCB is epoxy resin, which is more sensitive to laser energy. M1 and M6 use small pulse width and medium frequency. They can be marked with clear bar codes and two-dimensional codes for easy scanning.
