7. The Laser Marking Machine Purchasing Checklist
Use this checklist before you sign the purchase order: Pre-Purchase Decisions [ ] Identified all materials you need to mark [ ] Determined mark type (surface/anneal/engrave/color) [ ]…
8. Common Mistakes to Avoid
Mistake #1: Buying More Power Than You Need A 50W fiber laser costs 2–3x more than a 20W model. If you're only doing surface marking on steel, the…
Conclusion
Choosing the right laser marking machine doesn't have to be overwhelming. Start with your material — it determines the laser type. Then match your power needs to your…
1. How Each Laser Type Works
Fiber Laser (1064nm) A fiber laser generates its beam inside an optical fiber doped with ytterbium ions. Pump diodes excite the ytterbium, which emits at 1064nm. The beam…
2. Wavelength and Material Absorption: The Physics That Matters
Understanding why different materials respond to different lasers comes down to one principle: a material can only be marked by a wavelength it absorbs. Wavelength Best Absorbed By…
4. Best Application Scenarios for Each Type
