The actual technology that goes into todays laser engraver began to be developed in the early 1960s. It was back then that scientists and research engineers discovered that a high energy light source could be created, focused and used for various means.
Creating Light From a Gas
The gases that are used to create the original light source have a lot to do with the how a laser performs and by the way CO2 gas is used in laser engravers. So how is light created from a gas? It’s quite simple. They are created by agitating the molecules in the gas in an enclosed container, just the same way that light is generated from a neon light bulb.
A Far Cleaner and Safer Engraving Process
Laser engraving is often referred to a laser etching and unlike most all conventional methods of engraving or etching, no mask is required. That’s because unlike other methods of etching, no harsh chemicals or high temperatures are used in the laser engraving process.
The Capacity For Delicate Precision Work
Laser engraving also has many other inherent benefits when compared to standard engraving techniques. For instance, the actaul beam lends itself to far more precision work. Thus even very small and delicate items can be etched on with a laser engraver.
Other Benefits Of the Laser Engraving Process
Unlike other standard methods of engraving or etching, a laser engraver generates no dust or leaves no chemical residue. Also engraving on uneven surfaces is far more easily done by laser engraving. Thats because a light beam is far more easy to manipulate around and across these types of surfaces.
Transferring Images With a Laser Engraver
Amazingly, new technologies have been developed that allow people to automatically transfer images to surfaces with a laser engraver. The image is simply loaded into the engravers memory and with simply touch of a button the image is automatically engraved as it is on the surface of an object.
