Colour and Deep Engraving
All-in-One MOPA Laser Marking Machine
A MOPA source is a fiber laser with two more dials: pulse duration and frequency. Those dials turn a single machine into a colour marker on stainless steel, a black marker on aluminium and a deep engraver on steel. This cabinet carries 20W, 30W, 60W or 100W of that capability in a 35 kg body.

Pulse Duration
Why Two Extra Dials Change the Result
A fixed-pulse fiber laser gives you power and speed. A MOPA source also lets you decide how long each pulse lasts and how often pulses arrive, which is what separates a colour mark from a deep cut.
- Short pulse durationEnergy is delivered in a very short burst, so the surface oxidises without melting deeply. This is the regime used for colour marking on stainless steel.
- Long pulse durationEach pulse carries more energy for longer, so material is removed rather than tinted. This is the regime used for deep engraving on tools and moulds.
- Frequency sets the textureHigher pulse repetition produces finer, overlapping spots; lower repetition produces distinct, deeper spots and a rougher surface.
- Parameters are stored per jobRecipes are saved against the part number, so a colour mark is reproducible months later on another shift.
| Setting direction | Energy per pulse | Surface behaviour | Where it is used |
|---|---|---|---|
| Shortest pulses | Low, tightly packed | Thin oxide film, no measurable depth | Colour marking on stainless steel, black marking on aluminium |
| Medium pulses | Moderate | Dark annealed mark with slight relief | Serial numbers, logos and compliance labels |
| Long pulses, low frequency | High | Material removed, visible depth | Deep engraving, tooling and wear-resistant part marks |
| Long pulses, high frequency | High, densely packed | Fast coverage with moderate depth | High-speed line marking and large engraved areas |
The table shows the direction each adjustment moves the result, not fixed numbers. Exact pulse duration, frequency and power values depend on the alloy, its surface finish and the required colour, and we supply them after marking your sample.
Colour Marking
The Colour Range MOPA Unlocks on Stainless Steel
Colour on stainless steel is not ink and not a coating. It is a controlled oxide layer, and the machine is supplied with the recipes that produce it.
01
Black on Aluminium
High-contrast black marking on anodised and untreated aluminium, replacing printed labels and stickers.
02
Dark Blue and Deep Tones
Cooler oxide tones on stainless steel, used where a mark should read as part of the material rather than as print.
03
Gold and Bronze
Warmer tones for decorative panels, cutlery, sanitary ware and architectural hardware.
04
Multi-Colour Logos
Several tones placed in one pass, letting a brand mark keep its own colour scheme without any consumable.

Marking areas from 110 mm to 300 mm are achieved with matched f-theta lenses, so the field is chosen when the order is configured. Beam quality is quoted the way the source datasheet quotes it. Focal lenses, rotary axes and fixtures are specified per order.
Applications
Six Jobs a MOPA Source Does Better Than a Fixed-Pulse Marker
Everything below relies on the same thing: control over how much energy each pulse delivers and how it is spread.
Deep Metal Engraving
Durable marks for tool making and automotive parts, where a serial number has to survive years of contact wear.
Ceramic Marking
The 60W and 100W models mark ceramic bodies cleanly for home decoration, tableware and kitchenware.
PCB Marking
Sharp bar codes and Data Matrix codes on epoxy surfaces, replacing printed labels that fall off or smear.
Chip and IC Marking
Two by two millimetre codes engraved on electronic chips without damaging the substrate beneath them.
Crystal Line Engraving
Optimised for single-line work in crystal, producing even line weight for text and decorative patterns.
High-Speed Line Marking
For packaging and large-batch production, the 60W and 100W versions mark at line speed without dropping quality.
Hardware
Mechanical Choices That Reduce Failure Points
Three deliberate decisions keep this machine simple to own: a manual column, an aluminium bench and an air-cooled source.
- Imported high-precision galvanometerFast processing with strong interference rejection, so accuracy holds up in high-volume production.
- Manual lifting columnA handle raises and lowers the head. There is no motorised drive to fail, and maintenance stays simple.
- Aluminium workbenchHigh damping against vibration keeps the part still during fast passes, and the smooth surface is easy to clean.
- Air coolingHeat is carried away without a water circuit, so the source runs stable through long shifts.
- Low power consumptionFrom under 110W at 20W output to under 440W at 100W output, the cabinet is economical to keep running.
FAQ
MOPA Laser Marking Machine Questions
Yes. By changing pulse duration and frequency, the MOPA source builds different oxide layers on stainless steel, and those layers read as different colours. Permanent colour marks for branding and decoration are the reason most customers choose MOPA over a standard fiber marker.
Metals such as stainless steel, aluminium and titanium, plus many plastics, ceramics and certain composite materials. This range is why the platform is used from automotive work through to electronics and jewellery.
Depth depends on the material and the parameters you select. The 60W and 100W models deliver noticeably deeper engraving on metal, which suits tool manufacturing and automotive parts that need marks surviving heavy wear.
The interface is designed to be approachable on a first machine. Even so, we recommend reading the user manual or taking training before the first production run so the pulse and frequency settings start from a known point.
Keep the lenses clean, check the cooling system, confirm the optical alignment and follow the preventive maintenance schedule. Routine attention of this kind is what keeps a MOPA marker stable for years.
An efficient air cooling system carries heat away quickly and holds the laser components at a stable temperature, so the machine can run long shifts with fewer stoppages.
Yes. User-friendly marking software is supplied for design work, parameter adjustment and file import, and it integrates with the common file formats used in production.
The machine carries a 2-year warranty with free replacement of faulty parts. Troubleshooting and technical guidance are provided by our engineering team, and a 2-year term applies to the machine.
