1. The history of lasers can be traced back to Einstein's theory of light emission in 1916.
2. The laser was invented at Bell Labs in 1959.
3. An early use of laser engraving was directly burning images onto wood.
4. Compared with traditional engraving methods, laser engraving is faster & cheaper.
5. No toxic chemicals are used in laser engraving and no chemical residue remains afterwards.
6. With no tools to wear, contactless lasers deliver flawless character definition until the last engraving.
7. The laser is like a pencil, the beam emitted from it allows the controller to trace patterns onto the surface.
8. There is no inherent temperature to a laser beam. Heat is caused by the laser light hitting a surface and turning from light energy to heat.
9. Laser engraving can be used on a variety of materials to create fine works of art and personalised jewellery.
