The Science Behind Laser Engraving: How it Works

The Science Behind Laser Engraving How it Works

Laser engraving is one of the most modern, efficient and versatile methods for modifying the surface of a material. It can be used to create designs, to trace patterns and to refine the shape of an object. This technology has undergone a series of advancements over the years and it is often used during situations when precision and reliability cannot be taken for granted. Still, it is just as interesting to learn the science behind such a method. Let’s take a quick look at the principles behind laser¬†machine engraving.

Why Use a Laser?

There are two main benefits associated with a laser:

  • It is able to generate an incredible amount of heat.
  • Its focal point can be adjusted to a host of accurate diameters.

The heat produced by the laser beam will essentially vaporise a portion of surface material. This is sometimes referred to as “ablation” or “material removal”. The small recesses that are created as result represent the engraved surface.

Another important benefit associated with laser engraving is that it can be used with a wide variety of substrates. Wood, metal, vinyl, plastics, and polymers are a handful of well-known examples. As it vaporises a certain amount of material, there is also very little waste generated. The same cannot always be said for more traditional engraving methods.


Laser engravers are paired with advanced software packages in order to provide the operator with a superior sense of flexibility when tackling a project. Not only can object be viewed within a three-dimensional format, but tiny adjustments are able to be made so that the finished engraving is free from even the most minute of errors. On a final note, computer-aided engraving results in a higher level of efficiency. This is why it is often employed when tackling bulk projects

It is truly amazing that tiny photons of light are able to produce such incredible results within short periods of time. This is why a growing number of firms are employing such methods in order to create stellar results.
