Best Guide To Laser Engraving

With the large selection of laser engraving, it's no surprise that many people are confused about what is the best application for it. Many people don't even know that the term "laser" is an acronym – amplification of light by stimulated radiation – which describes the process of producing laser light.

The basic theory for this is simple. The amplifying medium (the material used to produce laser light) is excited by light or electricity to produce photons.  When the light reflected from inside collects enough energy, it exits through a semi-reflective mirror.

What is the difference?

This wavelength determines which laser to use for each application because the materials to be marked have different absorption capacities. If a material can absorb light, it can be affected by it.

Which one should I use metal for?

Most metals are highly reflective, so fiber laser is best. The much shorter wavelength means that less light is reflected off the surface, which means less energy is lost and the operation of the metal is easier. Metals absorb more than light energy, which changes their physical properties.

Which one should I use for non-metals?

Organic materials such as wood, acrylic, plastics, fabrics, and transparent objects are more suitable for CO2 because of their longer wavelengths and more flexibility. However, Nd: YAG and fiber lasers can also be used to mark some non-metals.
