Laser engraving got the start when scientists discovered they could create a light source, focus the energy, and yet has a tool powerful enough to affect a variety of materials.
If you've heard the term laser etching was just another name for laser engraving. In today's engraving industry, CO2 lasers, named for the gas used to create the light source, is the tool of choice.
As with many inventions of modern times, the laser out of the laboratory. They can be used to engrave/mark virtually any material. Laser marking is sometimes called laser etching but unlike conventional etching needs no masks or chemicals.
Marking is the most preferred method when someone wants immortality or aesthetics. The etching is the process of marking the material without cutting through using reduced power.
Etching creates a permanent message on the in-process or finished component. The ability to laser cut complex profiles can eliminate the need for additional surgery, make cuts very economical.
Marking of glass by CO2 laser while moving can be an excellent addition for industrial environments and applications for glass marking.
And when used to mark or etch glass and quartz replace traditional methods – these include sandblasting, ink pad printing, and etching. They also can provide excellent results for marking glass and provide a large reduction in operating costs and inventory costs.
