Laser engraving is a popular method for part and material marking since its emergence in 1964. A few years and a couple of laser technology advancements later, industrial laser engraving has become arguably the most sought-after method for part, component and material marking today.

Different Lasers for Different Uses

Before you buy a laser marking machine, you will need to figure out which laser best suits your needs. Here are the typical laser engraving machines in the market:

1. CO² Lasers

CO² lasers are gas lasers that employ a carbon dioxide mixture that is then stimulated electrically. These lasers boast relatively high efficiency and feature a very good beam quality. Best suited for working on non-metallic materials and most plastics.

2. Fibre Lasers

Fibre lasers engraving machines utilise a solid-state laser that produce an extremely small focal diameter, which results in an intensity that can be up to 100 times higher than that of CO² lasers. This attribute allows fibre lasers to work on metals by way of annealing and engraving, and high-contrast plastic markings.

3. Ultraviolet (UV) Lasers

The UV lasers employ ultraviolet light to mark and engrave a range of materials, primarily glass and plastics. For precision and micro-scale applications, such as micro-structuring and micro-drilling, UV lasers are the best choice!

4. Nd:YAG (Crystal Lasers)

Nd:YAG lasers are solid-state lasers that are doped with either rare earth ions or metal ions that enable the crystals to amplify light at the laser wavelength. This allows it to be well-suited for engraving, etching, and marking metals and plastics.
