Laser Marking FAQ

Laser Marking FAQ

What type of laser is best for my application?

Most marking lasers are CO2, YAG or Fibre (fiber). 

The CO2 laser has a high wavelength which makes it poor for metal marking applications as the laser radiation is often reflected by the target material. The YAG laser and Fibre laser have shorter wavelengths which not only provide better marking resolution, but are easily absorbed by metal.

The light source on the Fibre laser is completely sealed, preventing dust and particle contamination. This also enables longer distances between the control unit and the marking head, allowing the laser source to be situated remotely from the point of use - vital in some production line applications. It also reduces leakage, resulting in greater efficiency. Overall, the Fibre laser is cheaper to run and has fewer replacement parts than the YAG laser.

Because the YAG laser uses a lamp, it typically requires a liquid coolant. The Fibre laser is air-cooled, which makes the machine more compact and much easier to integrate into existing systems and processes.

Fibre lasers have essentially evolved from traditional YAG systems and are rapidly supplanting them. Fibre lasers are much more reliable and durable. YAG systems are becoming confined to specialist applications, particularly in the scientific sphere, and replaced by Fibre lasers in the industrial sector.

All of Pryor's laser products now incorporate the latest and best Fibre laser sources.

What are the operating costs of a laser marker?

The operating costs of Pryor’s fibre lasers are minimal. There are no consumable parts, so the only running cost is electricity and all units use less than 200W of electrical power while marking.
